How can I fix the “win32com.client” error?

The “win32com.client” error is due to a new Python version being installed without win32com, such as after an upgrade.

To fix this, please run the following commands in the folder of the new Python installation via Command Prompt as Administrator, from the newly installed Python directory (do this for both the 32-bit and 64-bit Python installations), for example, first cd (change directory) to C:\Program Files (x86)\Python39-32 or C:\Program Files\Python39-32 and then run:

python -m pip install pywin32
