Keywords: FPGA Express, Foundation Express, Synthesis, Options, illegal

Urgency: Standard

General Description:
This problem may be seen while running FPGA Express 2.0 on older versions of
Windows 95: From the Express GUI, selecting the Synthesis->Options pulldown
menu selection my result in a system error followed by a crash of the

"This program has performed an illegal operation and will be shutdown.

This issue is primarily seen on pre-OSR2 versions of Windows 95. You can
confirm the version used by entering an MS-DOS session for Windows 95 and
typing VER.

Windows 95 B (OSR2) will return: 4.00.1111
Older Windows 95 versions will return: 4.00.950


This issue can be solved by installing Microsoft Internet Explorer 4.0
(or 4.01). You do no actually have to use this software to fix the problem.

Go to http://www.microsoft.com/msdownload/iebuild/ie4sp1_win32/en/18174.htm
to install Internet Explorer 4.01.

Installing Windows 95 Service Packs will unfortunately NOT solve this issue.
