xloil python init failed

[huche6]

I am trying to use xloil to work with a 32-bit Excel version.
I downloaded in a virtual env python3.10 in a 32-bit version and installed xloil.
When I'm trying to run Excel, I am getting the following error:

[2024-06-10 14:34:31.528] [logger] [debug] [Main.cpp:299] Python importing xloil

The weird part is, if I activate my environnement and open a python consol, I can perform the faulty commands without problem. Do you have an idea from where the problem could come ?

I am working with:
32-bits Excel in Microsoft 365 Apps for enterprise
Python 3.10.4 in 32-bits
xloil 0.18.3
Windows 10

Great work for Xloil and thank you in advance !

P.S. It works without any problem with everything in 64-bits, I just have to use 32-bits version for a precise reason

Could you check where _ctypes.pyd lives in your python distribution? It's normally in the DLLs directory. I suspect that certain environment paths aren't getting correctly set because you're using an environment different from the standard one or anaconda. xlOil should be able to cope with different environments, so I just want to establish what's going on.

Thank you for your answer.
The _ctypes.pyd is in the DLLs directory

Could you try adding the path to the DLLs directory to your PYTHONPATH in your xloil.ini?
