The above is an error that occurs when the code below is executed in Faicham.

The pywinauto package was downloaded from the Windows power shell via the pip command and executed.
The Windows file you want to run is installed, and the directory is fine.
There is a suspicion that the PyCham Python console may not recognize the package, but it is wandering because it does not know how to check whether it is recognized.
I'd appreciate it if you could tell me what I'm missing or how to fix this error.
python
Check out the Python version.
It's a registered issue and there's a problem with the latest version of Python. The latest version here is the updated version of ctypes.
It seems that the type was changed when processing COM type in ctypes, but it seems to be taken care of in the next fix version due to Python issue.
This means that if the last fix version, such as 3.8.1 or 3.7.6, is up to date, it's a problem.
Downgrading Python to 3.8.0 or 3.7.5 is no problem.
