I had a similar problem with MS Word. You can see the mail trail in archives http://thread.gmane.org/gmane.comp.python.comtypes.user/153 Can you try using "Dynamic Dispatch" branch of comtypes? I suspect that something is corrupting COM vtable of "AutoCAD.Application" object. Thus, only IDispatch interface works (making win32com work) and direct method invocation used by comtypes fails. I resolved my problem by completely removing MS Office & reinstalling it. > As for debugging, what sort of debugger were you referring to?

I already saw the "QueryInterface" I think you need to build python from source with debugging enabled & use either Visual Studio or WinDBG or GDB to check values being returned by COM interface. This is just an arrow in the dark to check validity of COM interface table. You can print it using following code: >>> doc = app.ActiveDocument >>> import re >>> get_addr = lambda func: int(re.search('0x(?P<addr>[a-f\d]+)', >>> repr(func.im_func), re.I).group('addr'), 16) >>> from pprint import pprint as pp >>> pp([(i, get_addr(getattr(doc, i))) for i in dir(doc) if '__com_' in i and i >>> != '__com_interface__']) The offset between any two addresses within the same interface in the printed table should be same even on different machines. Can you run this code on the working & non-working machine and check if offsets differ?
