Yes, that's my 'c:\Users\Gisle\AppData\Local\py.ini'
in my case.

On that, I'm getting:
   Requested Python version (0) not installed

Is that '-0' some 3.9+ feature?

With a 'py', I get:
   Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 16:07:46) [MSC v.1900 32 bit (Intel)] on win32

With 'py -3.6' or 'py 3.8' I get the expected.
But with 'py -3':
   Python 3.8.9 (default, Apr 13 2021, 15:54:59)  [GCC 10.2.0 64 bit (AMD64)] on win32

Since I'm on a 64-bit Python, a 'py -3' totally seems to ignore
'py.ini', unless it says:
   [defaults]
   python3=3.6
   python3=3.6-32

Strange as always.

And yes, Mats Wichmann, I've tried a 'set PYLAUNCH_DEBUG=1'.
No help.
