Fix for module win32com.gen_py has no attribute 'CLSIDToPackageMap'

win32com.client.py

# If errors are found, do this
# clear contents of C:\Users\<username>\AppData\Local\Temp\gen_py
# that should fix it, to test it type
import win32com.client
app = win32com.client.gencache.EnsureDispatch('Word.Application')
app.Visible = True

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
