For what it's worth, importing dde works from within the MFC demo application Pythonwin.exe, located in site-packages\pythonwin, which is where you'll also find the MFC DLLs and manifest, along with win32ui.pyd and dde.pyd.

You'll probably find more help on the python-win32 mailing list:

Or file a bug report on the SourceForge bug tracker for pywin32:
