Whom do I contact for code support?

Questions should, in the first instance, be directed to the office or agent where your code was purchased, from where it may be escalated to senior staff if necessary.

All Itasca software is sold through Itasca offices and a network of agents throughout the world. If you do not know which office/agent sold your code, please use the office/agent locator to determine your primary source of technical support.

What is the best system configuration for my Itasca code?

Generally, the fastest computer with as much memory as possible. While we do not identify an optimum configuration, the following list provides minimums that should be present in order to obtain basic code operation. These are true for all Itasca codes.

• Target Platforms: 2000, XP, Vista
• Hard Drive: 100 MB (assuming full program installation)
• Memory (RAM): 512 MB
• Video: OpenGL capable graphics
• Processor: 1GHz or better

Where is the "Knowledge Base?"; Why not more "FAQs?"

Extensive "Knowledge Bases" and FAQs constitute the "free" portion of a software vendor's support policy; usually, to speak with support personnel is a pay-per-event process. Itasca software is supported in a free, person-to-person manner (see the Support Policy for a complete statement). As a result, there is no need for extensive internet-based support documentation. The information provided in these FAQs focuses on two areas: critical code operation issues (startup, keys, installation, etc.) whose resolution should not be delayed by having to wait for communication during normal business hours, and topics of occasional interest that are not immediately proper to the codes themselves (handling plots or making animations, for instance — the subjects of the next two questions).

What is the best method for moving my Itasca-code plot to my word processor/presentation/other software program?

In the last few years, Itasca has added significant new graphical output capacity to each of its codes. Soon all Itasca software will be able to create bitmap (BMP), jpeg (JPG), pcx (PCX), and enhanced metafile (EMF) output, as well as allowing for cut-and-paste operations through the Windows clipboard. As ever, the option to create PostScript (PS) output is available as well. The newer formats provide more user-friendly graphics than PostScript, the original — and once sole — option for graphical output. We recognize the importance of generating intelligible, professional-quality plots from our codes that may be efficiently included in reports and presentations; this is the very reason the new format options were added to the codes.

However, the greater number of choices for output has also increased the number of difficulties users encounter when moving from an Itasca code to the final destination program for that output. Unfortunately, we are unable to propose a "one size fits all" solution to these difficulties. We are not in a position to support or guide all users in the use of all their word processor, presentation, animation, or other software — where, as often as not, the real problems arise. Also, any graphics-based operation is contingent on a number of decisions and potential tradeoffs that are ultimately up to the user (e.g., is the final media going to be print or onscreen? is there a file-size sensitivity for the final media? what is the resolution capability of the output device? and so on ...).

That said, we are happy to share the following general guidelines that we ourselves observe when using our codes for consulting work at Itasca.

1. Avoid using the clipboard (using the SET plot clipboard command), primarily because it creates a situation in which the only "original" copy of the graphic output is that which has been copied-and-pasted into the destination software (for instance, such copied-and-pasted "originals" in Microsoft Word often are intractable to subsequent editing).

2. Don't hesitate to switch formats; if EMF output is not working well, use JPG or PCX files; if PostScript output creates oversized files, use bitmaps, etc.

3. Do not confuse the Itasca code with a graphics-editing package. If annotations, cropping, or other image editing is necessary, create a good-quality plot (PostScript, ideally) and make edits to it using a graphics-editing package. Itasca software is not designed to create image-art. Nor, for that matter, are word processor and presentation programs.

4. Use other tricks. One favorite is to use the "Print Screen" button on your keyboard. This puts a bitmapped copy of your entire screen on the Windows clipboard and can be pasted into another program (using the "Alt" key + "Print Screen" will capture only the active window, if you prefer).

What is the best way to make an animation using output from my Itasca code?

FLAC, UDEC, and 3DEC all contain a command, MOVIE, that allows the user to generate a sequence of PCX plots that are strung together and written to a DCX file that can be viewed using the "MOVIE.EXE" utility that comes with Itasca software. This is probably the fastest approach, but it is not available in FLAC3D, PFC2D, and PFC3D. Also, the MOVIE utility outputs DCX files (the animated version of the PCX format), which is an increasingly rarified file type. Given these shortcomings, it is easy to see why this question comes up. There is no single accepted way to make an animation, considering the plethora of animated file types (AVI, MPEG, MOV, GIF, QT, DCX, SWF, TIF, etc.) and the differences in the final presentation mode of the animation (on the web, in PowerPoint, in a MediaPlayer, embedded in a PDF file, etc.). Here, we share some of the techniques that we have used in the past as options for consideration.

Using a Bitmap Image Editor: Create a set of plots in a bitmap format (JPG, BMP, and PCX files can be output from all the codes). String them together in a bitmap-editor that will produce animated formats (we use Corel Photo-Paint to do this). Apart from the MOVIE command technique, this is probably the fastest method.

Get Around the PostScript Problem: If the initial set of output plots is in PostScript format, we have done the following: Batch-process the entire set into one PDF file using Adobe Acrobat. (Note: you need the full Acrobat program — not just the free Acrobat Reader — to do this.) Crop the resulting PDF file to obtain the desired image size. Choose the graphic selection tool, "Select All," copy the selection, and paste it into an animation building program. Repeat these steps for each page in the PDF file, and save the animation to the desired format.

Using PowerPoint: With slide timings set to zero seconds, a PowerPoint presentation becomes, in effect, an animation. PowerPoint will import all of the code output formats that are available in Itasca software (except PostScript — see the previous point for handling that problem). Since it appears that one predominant use for animations is in making presentations, we recognize the importance of PowerPoint relative to this topic. Consequently, we have built a PowerPoint file that contains a macro that automatically imports the user's entire set of graphic files, thus generating the final animation "all at once." The download available below also contains instructions on how to use the PowerPoint file.

Download the PowerPoint file (ZIP 38k)

The Really Quick "Look No Movie File" Movie: Many image-viewing programs — we use one called "ACDSee" — will automatically, sequentially display a specified collection of images. If the transition time between image views is set to zero seconds, a set of images can be viewed as an "animation" without ever being turned into an animation-format file.

It is worth remembering that (almost) any animation is just a set of rasterized (bitmap) images strung together into a single file with a timing mechanism controlling the rate of movement from one image to the next. Thus the critical questions are: What program will do the stringing? and, What is the final use/destination of the resulting file?

As noted above, the nearly-ubiquitous PowerPoint will create an "animation" but it will not output the slide show to an animation format. If an animation-format file is required, users will need a program that can import the original set of images and then output them to the desired format. Commercially available products from Adobe, Corel, Microsoft, Macromedia, and others will do this. Users are also directed to consider other, less expensive options, such as shareware or freeware, where there is an abundance of options ranging in price from $100 to $0. Entering "animation software" in any web search engine will quickly get you into this large realm of possibilities. Also note that most animation formats are proprietary: their proprietors desire their format to become the "standard" animation type and will offer low- or no-cost tools for building animations in that format.

How FLAC starts: General Description

The Windows executable flacw_sp.exe or flacw_dp.exe (single or double precision) must be started. Immediately, the JAVA runtime environment (JRE) must be located and loaded (this is done by loading "jvm.dll" from a properly formed JRE directory tree). Then, the graphical interface ("GIIC", which is a JAVA application) is started by locating and loading the "giic.jar" file, which contains the classes for the GIIC.

This process must occur in the order described. The critical steps in this process are locating and running the "jvm.dll" and "giic.jar" files; the majority of FLAC startup problems involves errors in one or both of these steps. Since the GIIC is separate from the FLAC executable, a method must be used to start it as well; the method for doing so has changed over time with different installations and is described for each of the respective "Detailed" answers below.

How FLAC starts: Detailed Description of Versions 4.00.222 through 4.00.293 as configured by installations from Itasca CD Versions 7A through 7E

The FLAC executable is started using a shorcut on the Start menu to the file "flacw_sp.bat" (note it is NOT started from flacw_sp.exe — attempting to do so will result in a flashing and disappearing command prompt). A command prompt ("DOS prompt") opens. The first line of the BAT file identifies the location of the JRE using an environment variable. Typically, the first line looks like:

set PATH=%giic%\jre\1.2\bin\classic

Here %giic% is an environment variable that was established during installation that stores the code installation location. Thus, the PATH of the first line evaluates to "c:\itasca\jre\1.2\bin\classic" (assuming the user accepts the default location of "c:\itasca" at installation time). At this location (that is, in the "classic" folder) the file "jvm.dll" should be located. If it is not, an error will result.

The second line of the BAT file is:

%giic%\flac\flacw_sp %1

This line starts the "flacw_sp.exe" file (per above, it evaluates to: "c:\itasca\flac\flacw_sp.exe". The "%1" is a placeholder for a numerical command line argument that may be used to allocate the amount of memory to be used by FLAC.

When the "flacw_sp.exe" is started, the command line argument "GIIC" is immediately passed to it by the file "flac.ini", which is located in the same directory as the executable. This argument starts the GIIC. Removing the word "GIIC" at the start of the "flac.ini" file would prevent the GIIC from automatically loading during FLAC startup — that is, it would allow FLAC to start in command-line mode.

The foregoing description utilizes default installation path ("c:\itasca") in discussing startup. The "%GIIC%" environment variable is formed at installation time and will store whatever location is specified when the code is installed — that is, a user-specified installation location is acceptable since the "%GIIC%" variable will accurately direct FLAC to the necessary files for startup. The description also assumes the user is starting "single precision" FLAC (the procedure is the same in all respects for the double precision version except the file names and BAT file commands use "dp" instead of "sp").

How FLAC starts: Detailed Description of Versions 4.00.294 through 4.00.313 as configured by installations from Itasca CD Versions 8A through 10A

The method is identical to the one above with the following exception: the FLAC EXE files (single, double precision) are located in a folder named "exe" below the main "FLAC" folder in the installation directory ("c:\itasca\flac\exe"). The BAT files are still found in the "FLAC" folder. As a result, the lines of the BAT file appear as follows:

set PATH=%giic%\jre\1.2\bin\classic
%giic%\flac\exe\flacw_sp %1 giic

The first line is the same as before. The second line now points to the location of the EXE file in the "exe" folder; also, the command line argument "giic" appears in the BAT file, which causes the GIIC to be loaded automatically on FLAC startup. Removing this command-line parameter would cause FLAC to start in command-line mode without the GIIC. Also, with the GIIC being started from the BAT file, rather than the "flac.ini" file, it is possible to start FLAC in command-line mode directly from the EXE file without causing an error (as occurred with the earlier startup method).

How FLAC starts: Detailed Description of Versions 4.00.314 through current as configured by installations from Itasca CD Versions 11A through 12A

FLAC is started from a shortcut on the Start menu that has as its target:

"c:\program files\itasca\flac\exe\flacw_sp.exe" giic

The quoted string points to the FLAC EXE; the word "giic" is a command line parameter for starting the GIIC (removing the word from the shortcut would cause FLAC to start in command-line mode).

When the executable starts, it searches, successively, for values in the Windows registry and then for the "GIIC" environment variable (this allows for backward compatibility with the older startup method). Either the registry values or the environment variable, when located, will provide the location of the JRE and the GIIC. An error will result if the information is not located, or if it incorrectly specifies the needed locations.

The location in the registry where the values are stored is "HKCU\Software\Itasca\FLAC". The values are strings the the following name/value pairings:

jrepath c:\program files\itasca\shared\jre\1.2\bin\classic
giicpath c:\program files\itasca\

The "jrepath" string indicates the location of the JRE; the "giicpath" string indicates the location of the "giic.jar" file. The "giic.jar" location is derived by combining the value of the string with the addition "flac\gui\", making a complete path that is "c:\program files\itasca\flac\gui". The "giicpath" stores the location where the code was installed, which may be changed by the user at installation time; the "flac\gui" portion of the path is NOT changeable by the user and thus may be added to whatever is stored in "giicpath" to correctly derive the location of "giic.jar". The preceding description has assumed that the default installation was used when installing; if the user specifies an alternate location at installation time, the registry strings and Start Menu shortcut are formed to reflect the user-specified location. Also, when installing on Windows NT, 2000, and XP, the installation will only work for the user-profile in which the installation was performed (see Q7 below).

"Can't load file jvm.dll"?

This error indicates that the "jvm.dll" file could not be found or loaded, which prevents loading the JRE, which is necessary to run the GIIC. To resolve the problem, the user should check the path specified in the PATH statement in the first line of the "flacw_sp.bat" files (see Q2 above), and/or check the path specified in the string stored in "HKCU\Software\Itasca\FLAC\jrepath" (see Q4 above). Either should indicate a folder in which "jvm.dll" can be found. If the file is properly specified and situated, there may be a problem with the overall structure of the JRE on the user's machine. In such an event, the user should either reinstall FLAC or try reinstalling the JRE alone (see Q6 below for information on doing this). There are other specific causes for this error described in the next three questions.

Can't load file jvm.dll: FLAC won't run on Pentium 4 (P4) system

[this topic is specific to installations of FLAC from CD versions 7A, 7B, and 7C; the problem described is corrected on CD versions 7D and higher]

The Java Runtime Environment (JRE) Version 1.2.2 that installs with FLAC 4.0 does not work on P4 systems. Most commonly the error reported on startup is "Can't load jvm.dll", but other error messages are possible. To resolve this problem, users will need to acquire a new JRE (5.3M file) from Sun. The correct JRE is the Java2 Runtime Environment v 1.2.2_011, available at:

http://java.sun.com/products/archive/j2se/1.2.2_011/jre/index.html
(click the "download" button, accept the license agreement, and choose the US English version for Windows platform)

Important Note: There are newer versions of the JRE, but currently the GIIC should only be run using JRE 1.2.2_011.

After download, when running the installation, YOU WILL NEED TO CHANGE THE INSTALLATION'S SUGGESTED DEFAULT to the location where FLAC and the JRE were originally installed. A standard (default) installation location from Itasca CDs 7A, 7B, and 7C is:

c:\itasca

When installing the JRE 1.2.2_011 update from Sun, the installation program will suggest installing to this location:

c:\program files\Javasoft\JRE\1.2

To properly install the JRE to work with FLAC, this location should be changed to:

c:\itasca\JRE\1.2 [assuming the default location per above]

If the installation of FLAC was put in a user-specified location, then the "c:\itasca" portion of the path above must be changed to the same user-specified location that was entered when installing FLAC.

Can't load file jvm.dll: FLAC won't start on Windows NT, 2000, XP

[in this case specific to FLAC installations from CD version 11A and 12A]

If the user profile when starting FLAC is not the same as the user profile that installed FLAC, an error will occur on startup. (This kind of error is common for users who have system administrators perform their FLAC installation but then try run using their own, differing user profile). To resolve, the user profile will need to have the "jrepath" and the "giicpath" added (see Q4 above. Alternatively, the code could be re-installed under the user's profile, but this does require that the user's profile be given administrator privileges on the machine.

Can't load file jvm.dll: FLAC won't start on a network

[in this case specific to FLAC installations from CD version 11A and 12A]

FLAC cannot be started from a remote machine on a network because the local machine does not have information (registry entries) to locate the "jvm.dll" (JRE) and the "giic.jar" (GIIC). The HKCU of the lcoal machine must have the "jrepath" and "giicpath" strings created in a "HKCU\Software\Itasca\FLAC" section of the registry (this location will also have to be created). The full network path corresponding to the EXE being used must be included. For instance, to start FLAC on a computer with the network name "Zeta", where the EXE is located at "c:\program files\itasca\flac\exe\flacw_sp.exe", the necessary strings/values are:

HKCU\Software\Itasca\FLAC\jrepath =
\\Zeta\c\program files\itasca\shared\jre\1.2\bin\classic
HKCU\Software\Itasca\FLAC\giicpath =
\\Zeta\c\program files\itasca

When started this way, FLAC is run as a process on the local machine, it is not run from the remote processor. The hardware lock necessary to run the code must be on the local machine, not the remote machine from which the code is being pulled.

"Java/GIIC failed to initialize. GIIC canceled."

This error indicates that the "giic.jar" file could not be found or it could not be loaded. To resolve the problem, the user should check the first line of the "flacw_sp.bat" file. Relative to the line "set PATH=%giic%\jre\1.2\bin\classic", the "giic.jar" file will be located in "%GIIC%\flac\gui" (see Q2 above for a fuller description for resolving the %GIIC% variable). Alternately, the user should check the path specified by the string in "HKCU\Software\Itasca\FLAC\giicpath" (see Q4 above). The string should indicate a folder in which "giic.jar" can be found when the additional string "\flac\gui" is added to it. If the "giic.jar" file is properly specified, then the cause of the error may be a corrupted file. In this event, the user should either download and install the latest version of FLAC from this web site or re-install from the CD. This error message is often followed by a line like this: "Execption in thread "main" java.lang.NoClassDefError: flac/gui/main/MainFlac". This is the error reported by JAVA and is part of the same problem; the last part of the message is useful, because it indicates that JAVA is trying to load the main class in the "giic.jar" file from the location "\flac\gui\main\MainFLAC". A correctly formed path would include the full location, that is, "c:\program files\itasca\flac\gui\main\MainFLAC". In other words, the error message is indicating that the correct path to the "giic.jar" file is not being used by FLAC when starting.

Why does FLAC appear to start then disappear?

When the FLAC executable and the GIIC are started together (as in all the startup methods described above), first the EXE is loaded into a command prompt ("DOS box"). Then, if an error occurs while trying to initialize and start the GIIC, it is reported on the command line, and then the command prompt is automatically closed. This behavior is not universally consistent across Windows platforms and under all error conditions. Some of the more common instances of the behavior include: installations of FLAC from CD versions 7A-7E would exhibit this behavior if the user tried to start FLAC directly from the EXE file instead of from the BAT file; startup with a faulty %GIIC% environment variable could cause the behavior; startup on a JRE that is incompatible with the processor (see Q6) could also cause the behavior.

Since the error message that occurs on startup is in fact reported on the command line, it is helpful to get around the "disappearing" problem in order to determine what the error message is. To do so, users should start FLAC "manually": open a command prompt (Start-->Programs-->Accessories-->Command Prompt), type in the location of the FLAC EXE file (for example, "c:\itasca\flac\exe\flacw_sp.exe"; bear in mind that quotes around the entire path may or may not be required). This should start FLAC in command-line mode. At the "flac:" prompt, type "GIIC". This should re-create the error condition that occurs on startup, but the window will not disappear and the error message may be obtained.

How do I change the amount of memory utilized by FLAC?

By default, the amount of memory that FLAC requests from the operating system is 8 Mbytes(single precision) and 24 Mbytes (double precision). For BAT-file based startups (see Q2 above), replace the "%1" in the BAT file with the desired amount of memory, in megabytes. For EXE-file based startups (see Q4 above), modify the shortcut to the EXE on the Start Menu by adding the desired amount of memory, in megabytes, after the word "giic" at the end of the target string. (Right-click on the shorcut in the Start menu and choose "Properties" from the resulting popup menu in order to make this adjustment.)

How do I start FLAC in command-line mode?

A non-GIIC startup for FLAC depends on the installation configuration. Either: 1) remove the command "giic" from the "flac.ini" file (see Q2 above), 2) remove the command line argument "giic" from the BAT file (see Q3 above), or 3) remove the command line argument "giic" from the FLAC shortcut on the Start menu (see Q4) above.

What is the Itasca CD?

It is the CD-ROM from which all Itasca software is installed. It also includes electronic copies of the code manuals, and code demonstrations. It is freely available to anyone on request. Only licensed users will be able to run Itasca codes that are installed using the CD-ROM. Unlicensed users may install the codes and run them in "non-cycling" mode, which disallows solution cycling. Non-code users may also find the information in the manual and demos useful for code evaluation purposes.

What is the CD-ROM Version?

The CD-ROM is serialized, to provide tracking information and to assist in customer support. The number identifies the version of the Itasca CD-ROM. The number is incremented each time a code is newly added or upgraded on the CD, or if the installation routine for the codes is changed. The current version is 20C.

What does the version number mean?

The two digits at the beginning of the number represent the major version. The major version number only changes when a code is added or receives a major upgrade. The letter indicates the sub-version, which may indicate either minor code updates, bug fixes, or changes to the installation routine.

How do I identify the version number of my CD-ROM?

1) Look at the transparent innermost ring of the disk itself; the version number is written there
2) Using Windows Explorer (or any file system viewing utility), check thevolume name of the disk; the version number is contained in the name of the volume.

Left: the version is written on the disk itself Above: the version number is contained in the name of the CD volume

Are the changes made from version to version of the CD-ROM documented?

Yes. The "readme.txt" file in the root of the CD-ROM contains basic user instructions for the CD-ROM and, in its last section, has a modifications list. Incidentally, viewing this list would also be a way to determine the version of the CD, since the final entry will indicate the current CD-ROM version.

What codes are installed from the current version?

Itasca20C installs the following codes:

• FLAC 5.0
• FLAC/Slope 5.0
• FLAC3D 3.1, 32-bit and 64-bit
• UDEC 4.0
• 3DEC 4.1, 32-bit and 64-bit
• PFC2D 3.1
• PFC3D 3.1

Is the latest version of my code on the CD-ROM?

The version of the code on the CD-ROM is the latest version that has gone through the full QA procedure. As this procedure is very lengthy it is not performed each time a minor bug is fixed. Because of this it is very likely that a newer version of the code is available from the Download section of this site. This is true even if you have just purchased the code. It is always useful to check this site for code updates.

Can I update my CD-ROM?

Yes. Itasca will freely provide the latest CD-ROM to users on request. If you are a user of any of the codes above, you may obtain a free copy of the latest CD, which contains the current best-practice installation for these codes.

Should I update my CD-ROM?

Since it is impossible to guarantee that today's installation will work on tomorrow's computers, updating your CD-ROM is usually the simplest way to ensure you can correctly install your Itasca code. However, frequent updating of the CD-ROM (from one sub-version to the next, for instance) is probably overkill. Check the list of "known issues" below to help determine whether your CD-ROM should be updated. Consider updating your CD-ROM when the major version number of the CD-ROM changes; seriously consider updating your CD-ROM if it is more than one major version number removed from the current CD-ROM.

Known Issues

Versions up to 4C: contained an error when uninstalling from Windows NT. This problem impacts: all codes. NT users who need to uninstall should do so manually (do not use the uninstall program in the "Add/Remove Programs" applet). Reinstall with a CD Version 4C or later, if possible.

Versions 7A, 7B: did not properly install Unikey drivers for the code security system. This problem impacts: FLAC3D 2.0, PFC2D 2.0, PFC3D 2.0. Users of these codes who have a 7A or 7B CD should update.*

Versions 7A, 7B, 7C: contained a Java Runtime Environment that does not function properly on computers that use a Pentium 4 processor. This problem impacts: FLAC 4.0. Users of FLAC 4.0 who have a Version 7A, 7B, or 7C CD-ROM should update.

Versions up to 10A: may exhibit security key errors when installing to some computers running the Windows XP operating system. This problem originates with Rainbow Technologies. An updated driver installation is available from the About the Keys page. Versions 10A and newer do not require an updated driver.

Obtain the latest key drivers

These downloads may be used to install the most up-to-date key drivers that Itasca supplies for use with its codes. In most cases, only the Rainbow key drivers are necessary. Versions earlier than the current version of FLAC3D (versions 2.0 and earlier), PFC2D and PFC3D (versions 2.0 and earlier) may also require the Unikey drivers. Note these downloads may be saved to and run from any location on your computer.

Rainbow Key drivers (for Windows 95, 98, ME, NT, 2000, XP; size: 5.9M)
Unikey Key drivers (for Windows 95, 98, ME, NT, 2000, XP; size: 349k)

What is my "key" and why is it necessary?

The "key" (interchangeably referred to as a hardware lock or dongle) is a security device that prevents the operation of Itasca codes on machines where it is not present. The key is a dongle that is attached to either the LPT1 or USB port at the back of your computer. The key is serialized to your licensed version of the Itasca code you are using. Due to a changeover in 1998, users of newer versions of Itasca software will have Rainbow keys (distinguished by a tan case for parallel keys, or purple for USB keys). Users of older versions will have Unikeys (they have a black case).

Why does my code report an error locating the hardware lock on my machine?

What: A key-related error is reported on starting the code, which prevents the code from being used.

Why: These errors occur when there is no key present on the user's machine. These errors also result from a faulty installation of the key drivers, or if the driver files have become corrupted/damaged/lost.

Fix: First check to see if your key is properly connected to your computer. If the key is properly connected, download and install the latest key drivers. Please note the drivers for both Unikeys and Rainbow keys must be installed, regardless of the individual type of key you have. Installation instructions are included in the download files. If there is still a problem after installation of the drivers, please contact Itasca.

Why doesn't Windows XP find my key?

Some computers running Windows XP experience difficulty in accessing the key using drivers that are distributed on the Itasca CD (versions up to 9C; see About the CD-ROM for information on CD-ROM versions). This can be solved in most cases by obtaining and installing newer Rainbow key drivers. Note you must have administrator privileges to update the drivers in Windows XP.

Security key errors on a Toshiba laptop

Toshiba laptops have been particularly error-prone when operated with Sentinel security keys. The following information is obtained directly from the Rainbow Technologies web site — the manufacturer of the Rainbow keys.

Itasca code users who are unable to get their Toshiba laptops working with the Sentinel keys despite trying the above recommendations may wish to contact SafeNet (formerly Rainbow Technologies) directly for further support:

Are there configurations that will interfere with key operation?

Can I piggy back it with other sofware dongles? The only limitation (known to Itasca) for daisy chaining parallel dongles is a power issue. Technically the power is supplied by the printer. If a printer is not attached, the port does supply some power but may not be able to handle multiple keys.
Lease keys should not be connected with other keys. FLAC3D, PFC2D, and PFC3D versions dated prior to September 2001 should also not be used with multiple keys attached. This will interfere with proper key operation and may result in destruction of one of the keys.

Can I plug the key somewhere into the chain of zip/CD/port connections? Storage devices may damage Unikeys. This has not been reported as a problem for the Rainbow keys.

Can I plug the key into the second port? Our testing with a second parallel port showed no problem or necessary modifications when using a Rainbow key. To get a Unikey to work on a second port, the line SSI_LPT=2 had to be added to SYSTEM.INI. The DDINST32.EXE file (the Unikey driver installation file) would not successfully make this modification, although the instructions claimed it could do so.

What if my computer does not have a parallel port?

For a flat shipping/handling fee, Itasca will trade your parallel key for one that will work through your USB port.

• How do I overlay a DXF image on a FLAC 4.0 grid using the GIIC?
• Why does FLAC3D report the error "Error in system date/time - check your system date and time?"

How do I overlay a DXF image on a FLAC 4.0 grid using the GIIC?

1. Click on the [Draw] menu from the [Model] pane.
2. Click on [Images], and then [DXF].
3. A dialog box will open and allow you to browse your folders and find the desired DXF file.
4. If, for example, you have a DXF file named CIRCLE.DXF, click on this file and open it.
5. The figure should nw appear in the [Model] view.
6. If you do not see it, click on [Reset] (full view) in the [View] menu. You can also zoom in on the view (with [Zoom] box) or translate it (with [Translate]). Also, click on [Fix View] in the [View] pane to fix the oreientation of this view.
7. Now, create the FLAC grid. For example, use the [Simple] tool from the [Build] tab, and adjust the coordinates of the grid to encompass the DXF image. You should now see the "virtual" FLAC grid with the DXF image superimposed. When the [Execute] button is pressed, the commands are sent to FLAC to create the grid.
8. You can make a plot of the grid with the DXF image by using the [Model] tool in the [Plot] tab. Click on [Plot Items/Geometry/dxf] to open a dialog to access the DXF image, then click on [Plot items/Geometry/grid] to add the grid plot. Both items should be added to the plot items list. Then click [OK] and the plot will be created. This is the same as PLOT DXF CIRCLE.DXF GRID.

Why does FLAC3D report the error "Error in system date/time - check your system date and time?"

This problem only effects users that have a leased key. A system variable "timezone" (that is used in FLAC3D) gives two different values in DOS and Windows systems. This system discrepancy was noted and corrected (in version v2.00.092) after FLAC3D version 2.0 was put on the official Release CD (the CD release version is FLAC3D v2.00.071). Users should therefore download the latest version of FLAC3D v2.0 (DOS or Windows) from our website after their installation of the FLAC3D v2.0 from the Release CD.

On versions previous to 2.00.92, if the user runs the DOS version of FLAC3D and then tries to run the Windows version, the System Time/Date error will result from incorrect data being written into the security key.

This error can be rectified:

1. If the user obtains a new password from the sales agent that resets the security key parameters.
2. If the user waits for a day and then starts the latest DOS/Windows version of the code after updating it through our website.

• Windows XP
• Windows XP x64
• Windows Vista (32-bit and 64-bit)

Other and older operating systems (Windows 2003 Server, Windows NT, Windows 95, Windows 98, Windows ME) are not supported. Itasca software may run on these platforms, but as they are not supported Itasca provides no assurance of compatibility with them.

Itasca's 32-bit codes are operable on 64-bit computer systems, however, they are not 64-bit programs and do not have 64-bit addresses.

Known Issues

• The Iv option for PFC3D is not compatible with Windows Vista

Vista compatibility - It is strongly recommended that users obtain the latest Itasca CD (currently version 20C) when installing to Windows Vista. Earlier versions of the CD pre-date the release of Vista and have exhibited a variety of problems and errors when being used to install current release versions of Itasca codes.

At times key-related errors may be resolved by updating to the latest version of the Sentinel SuperPro drivers. These are available at Sentinel Technical Support, in the Sentinel-Super Pro section. When obtaining drivers be sure to download the latest drivers that are compatible with your operating system.

If you are experiencing problems that are not resolved by the information available here, feel free to contact Itasca for assistance with your issue.
