Sorry, I should have included more info. I'm not registering a DLL,
at least not directly. The extension I'm registering is a class in a
Python script, much like the "context_menu.py" example. I was under
the impression that it gets registered to run via pythonw.exe when the
context menu command is used, and wouldn't have the 32/64-bit DLL
issue. I could definitely be mistaken.
I took a closer look at the registry entries created by registering it
for 32-bit Explorer. It has a CLSID registry key called
InprocServer32 with a value of "pythoncom26.dll". Suggesting I need
to use the 64-bit build of that DLL, perhaps?
On the other hand, it also has a LocalServer32 entry with a value of:
C:\Python26\pythonw.exe
"C:\Python26\lib\site-packages\win32com\server\localserver.py"
{d6d38fd0-77fb-11df-93f2-0800200c9a66}
I've looked through the python code for
win32com.server.register.RegisterServer, and it appears as if I may
need to use Python x64 + pywin32 x64 if I want to add a Python-based
contextmenu for Explorer x64. But I'd be very happy to learn how to
register it on Exp64 using the 32-bit stuff...
Thanks.
