@amarines2605 - I've deleted gen_py countless times as everyone seems to recommend... the quickfix for microsoft 365 was the piece I was missing. Thank you for the solution.
Remove-Item -path $env:LOCALAPPDATA\Temp\gen_py -recurse
work for me!!!!!!!!!!!! ty!
From PowerShell one can use:
Remove-Item -path $env:LOCALAPPDATA\Temp\gen_py -recurse
Thank you Plus.
After deleting the content of C:\Users\AppData\Local\Temp\gen_py, you have to restart the computer. Then you can launch in Python or Spyder :
`import win32com.client as win32 from win32com.client import constants, Dispatch
excel = win32.gencache.EnsureDispatch ("Excel.Application") word = win32.gencache.EnsureDispatch("Word.Application") `
Just deleting the contents from
AppData\Local\temp\gen_py
worked for me
