8.3.11 TROUBLESHOOTING
This section provides some procedures for troubleshooting the 489PC when troubles are encountered within the Windows
environment (for example, General Protection Fault (GPF), Missing Window, Problems in Opening/Saving Files, and
Application Error messages).
If the 489PC software causes Windows
system errors:
1. Check system resources:
• In Windows 95/98, right-click on the My Computer icon and click on the Performance tab.
• In Windows 3.1/3.11, select the Help > About Program Manager menu item from the Program Manager window.
Verify that the available system resources are 60% or higher. If they are lower, close any other programs that are not
being used.
2. The
threed.vbx
file in the Windows directory structure is used by the 489PC software (and possibly other Win-
dowsâ„¢ programs). Some older versions of this file are not compatible with 489PC; therefore it may be necessary to
update this file with the latest version included with 489PC. After installation of the 489PC software, this file will be
located in
\GEPM\489PC\threed.vbx
.
3. To update the
threed.vbx
file, locate the currently used file and make a backup of it, e.g.
threed.bak.
4. A search should be conducted to locate any
threed.vbx
files on the local PC hard drive. The file which needs replac-
ing is the one located in the
\windows
or the
\windows\system
directory.
5. Replace the original
threed.vbx
with
\GEPM\489PC\threed.vbx
. Ensure that the new file is copied to the same
directory where the original one was.
6. If Windowsâ„¢ prevents the replacing of this file, restart the PC and replace the file before any programs are opened.
7. Restart Windowsâ„¢ for these changes to take full effect.
