Kernel error win32api

[lueenavarro]

After launching any notebook, I get the following error.

Traceback (most recent call last):

Rumors abound there's an installation glitch in the 225 build of pywin32. Have you tried conda install pywin32?

[afvca]

Don't know how you installed pywin32, but you may be missing the system files.

Try downloading a precompiled wheel from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pywin32

And install pywin32 system files, cd into your PYTHONPATH, and run python.exe Scripts/pywin32_postinstall.py -install from an elevated command prompt.

Had the same issue and pip uninstall pywin32 and installing it again helped. conda install pywin32 didn't work, however.

[JStuckner]

Can confirm @ValentinVerschinin solution worked. Thanks for trouble shooting this several hours before me!

[Besong]

Thanks @ValentinVerschinin it worked!.

According to pywin32 github you must run

pip install pywin32

and after that, you must run

python [environment path]/Scripts/pywin32_postinstall.py -install

After hours this worked for me!

It also worked for me. Cheers bro!

Too many successes - time to close! 😄

The easiest thing for me was to pip uninstall it and then conda install it.
