I created a fresh Python 2.7 environment with pywin and py2exe and stripped down my overlay handler to the basics to better troubleshoot.
Running my script (command line or in PyCharm) registers everything correctly, just like before, but running the py2exe generated EXE seems to be registering but no overlays are appearing, which looks just like what happens when I restarted explorer.exe in my previous attempt (logged messages during registration, plus a manual check of the registry look good but nothing generated by IsMemberOf. I'm going to try generating a DLL and manually registering following the example here: http://stackoverflow.com/questions/4619701/python-64-bit-dll-com-server-registration-problem-on-64-bit-windows-7 It looks like this example came out of a mail thread with you back in 2011 so I'll try to follow the advice there and report back. Thanks again for the help Mark.
