WIN32S problems after installing Foundation (win32s v1.30a) - OE20.EXE, unexpected DOS error 21
Win32s 1.30a, which is installed with the Xilinx Foundation Series software, has compatibility problems with some Windows configurations.
Symptoms of an incompatible Windows configuration include:
1. In the Foundation Schematic Editor, you cannot push into an HDL-based macro. 2. The XACTstep Design Manager reports an error regarding OE20.EXE. 3. Any win32s program (such as Freecell) reports "Unexpected DOS error 21" or "Insufficient memory to run program".
Install win32s 1.30c. This is supplied on the Foundation 6.0.1 CD.
Remove win32s v1.30 from the PC. Xilinx provides a batch file on the XACTstep CD to do this (\XBBS\UTILS\RMWIN32S.BAT). Exit Windows and run the batch file. Follow the instructions on the screen to remove win32s from your system.
Start Windows. Select File->Run and run the setup program from the CD (\win32s\support\1_30c\disk1\setup.exe).
