I've downloaded psw-ce-220.127.116.11.zip on my computer (Windows 7 64-bits). I unzipped the folder and tried to launch workbench.bat. My problem is that nothing happens.
The same .zip was 'installed' on a Windows 2003 Server and there it runs.
I've searched the internet and found that P.S.W. is compatible with Windows 7.
What I'm doing wrong?
