OS: x64 Windows 10 Professional 1903 fresh installation (with latest updates)

Python 3.8 app (final version 3.8.0, not RC) installation from Microsoft Store adds two shortcuts to the Start menu:

• Python 3.8
• IDLE (Python 3.8)

Clicking the "Python 3.8" (python3.8.exe) starts Python interpreter - all fine and good.

Clicking the "IDLE (Python 3.8)" (idle3.8.exe) displays only the error message "MSVCP140.DLL was not found" (I do not remember exact sentence, because eventually I manually installed Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019).

I know what this is - the fix that went into the console executable didn't make it into the windowed executable.
