the only solution I can see is to downgrade from python 3.10 down to 3.9

pywin32 version 302 (NOT pypiwin32, which looks like a mistake from 2018) was uploaded to PyPi on October 10, 2021, and states in the change log:

  • Support for Python 10, dropped support for Python 3.5 (3.5 security support ended 13 Sep 2020)

Demo (using PyLauncher to update my 3.10 install):

C:\>py -3.10 -m pip install pywin32

Make sure to run the Scripts\pywin32_postinstall.py from an administrator command prompt as well to register it properly. Make sure it runs in the context of the 3.10 installation as well (again using PyLauncher):

C:\Python310\Scripts>py -3.10 pywin32_postinstall.py -install
