how to register a 64bit python COM server

Question

ahk code: ComObjCreate("{C2474B5A-5E9D-484D-BDFD-20A100183426}")

this works in AutoHotkeyU32.exe, but not in AutoHotkeyU64.exe
error message is: the specified module could not be found.

full code is here: How to program hotstrings in python like in autohotkey

I call my SymPy functions using ahk hotkeys. I register the python script as a COM server using pywin32 and load it using ahk.

Answer 1

you'll need pywin32, but don't download using pip install pywin32
download from https://github.com/mhammond/pywin32/releases
OR ELSE IT WON'T WORK for AutoHotkeyU64.exe, it will only work for AutoHotkeyU32.exe.
make sure to download amd64, (I downloaded pywin32-300.win-amd64-py3.8.exe)

EDIT: now I understand why it didn't work
I think it CAN work when using pip install pywin32 if you register it correctly.
you have 2 choices:

1. register it correctly as shown here How to program hotstrings in python like in autohotkey :
   do NOT use UseCommandLine() , use RegisterServer(clsctx=pythoncom.CLSCTX_LOCAL_SERVER, ...)
2. after server has been registed using UseCommandLine() , delete the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{C70F3BF7-2947-4F87-B31E-9F5B8B13D24F}\PythonCOMPath\InprocServer32
   
   replace {C70F3BF7-2947-4F87-B31E-9F5B8B13D24F} with your own CLSID

(I think) there is no need for
key: InprocServer32 :
Name : (Default)
Type : REG_EXPAND_SZ
Data : pythoncom39.dll ,
also, requiring it makes it fail

(I think) There's no need because it actually uses LocalServer32 (which is also a key)
mine is:
Name : (Default)
Type : REG_SZ
Data : C:\PROGRA~3\Miniconda3\pythonw.exe "C:\ProgramData\Miniconda3\lib\site-packages\win32com\server\localserver.py" {C70F3BF7-2947-4F87-B31E-9F5B8B13D24F}

localserver.py is the one doing the COM stuff, to prove it, replace pythonw with python . you will the window when it's ran.
