OK. Are you calling CoInitializeEx(COINIT_MULTITHREADED)? If not you
may be in for some subtle bugs.

However, I don't think thats the cause of this.

Thats very strange. Lines around 28 of __init__ are...

      try:
        import gencache
        if gencache.GetModuleForCLSID(resultCLSID) is not None:


And the module gencache definitely includes GetModuleForCLSID, so that
doesn't explain the AttributeError.

Can I suggest you change this to....

      try:
        import gencache
	raise 'eh?', (gencache,dir(gencache))
        if gencache.GetModuleForCLSID(resultCLSID) is not None:

That should tell you exactly what gencache is, and what symbols it
contains. Hopefully that should be a hint to the real problem.

(ps. Then remove that line when you are done, or youll find all your
other pythoncom scripts are broken ;-)
