[Zope] COM-Error: CoInitalize was not called

Hello guys, I am programming a custom COM-Method. However after I call win32com.client.Dispatch('NameOf.ComObject') a COM-Error raises containing "CoInitalize was not called". I am working with Zope 2.6.0 on W2K and have the win32com, the win32comext and the Pythonwin modules installed in $ZOPEHOME\bin\lib. I have copied the modules from a working ActivePython installation. If I execute the method from the Pythonwin command line, everything works fine. Whats wrong?
