Revision history [back]

Are you using Version 30 or new version? For the version 30 or earlier, it should not use psspyc.pyd. In the PSSBIN folder, you should be able to find a file named psspyc.dll. For version 31 or newer, it uses psspyc.pyd. For the newer release, it has some bugs with win32 compatibility. Upgrade your PSS/E to the Version 33.4, which resolves most of the compatibility issues.
