I installed pywinauto
using pip install pywinauto
.
OS: Windows 10
Python: 3.6.2
When I run python
and try to import pywinauto
, I get the error:

Any ideas how to fix this?

Answer
I have the same issue today and fixed it by pip install comtypes==1.1.7
.
It caused by comtypes library which release a new version 1.1.8 at Dec.26. Downgrade to previous version, it works well now.
