[Zope] ZSwGenerator Error Parsing Template Win32 Operational Error

Hi, I am trying to useZSwGenerator on win2000 with Zope 2.3.3. But I allways get: Error Parsing Template Win32 Operational Error while trying to add an ZSwGenerator object. Is the a special place (path) where swiftgen.exe must be placed? I have imported the ZSwdemo.zexp but when i try to view swfdemo I get: Problems executing external program Win32 Operational Errorany suggestions? Thanks Jens
