Roger is quite correct in saying that you cannot load a 32-bit DLL into a 64-bit process (or vice versa). That is an incontrovertible fact. COM servers come in two styles: "in-process" and "out-of-process". An in-process server loads as a DLL in your process. An out-of-process server runs as a separate application; a stub DLL gets loaded into your process that uses Remote Procedure Call to make requests into the separate application. Excel is an out-of-process COM server. That means it doesn't care about your bittedness. I don't know about ZwCAD, but it might be the same. If the COM server you are trying to access only supports "in-process" serving (and many do), then you cannot use it from 64-bit Python. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
