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

The following code will only delete the folder of the cache - it worked for me, but the better solution is "shutil" - earlier in this topic

try: xl = gencache.EnsureDispatch('Excel.Application') except AttributeError as ae: error_message = str(ae) if 'win32com.gen_py' in error_message: start = error_message.find('win32com.gen_py.')+len('win32com.gen_py.') tmp_em = error_message[start:] end = tmp_em.find("'") the_dir_to_remove = tmp_em[:end] if the_dir_to_remove in os.listdir(win32com.gen_path): win_gen_path_to_rm = win32com.gen_path+''+the_dir_to_remove print("Removing: ", win_gen_path_to_rm) recurcive_removal(win_gen_path_to_rm) else: print("unknown error of win32com") else: print("unknown error") print(ae)

@HeroOfStorm When putting code, it's better to put between triple backsticks with an optional language, like:

```python
... Your code
```

This will:

• Ensure correct indenting
• Avoid __gen_path__ being replaced by gen_path (with bold and without underscores)
• Provide syntax Highlighting

Hi, in my case, sudenly, it happens again, i tried all metods showed here and no luck, in the end, i realized that my microsoft 365 apps for enterprise had beed updated few days ago in windows control panel, just right click, change, quick repair, and thats it, it worked again!!

regards

@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
