Assuming self.CLSID is the CLSID of the *object*, not the *DLL*, this 
should work.

Have you run regsvr32.exe on the DLL?  Can you create the object from 
another VB program, or using WSH?

The CLSID of the DLL will never work - it must be the object's CLSID.

I assume you have a good reason for using pythoncom.new() over 
win32com.client.Dispatch()?
