And what to do if the Pylauncher itself seems confused or the
Registry settings for PythonCore is messed up? The WOW64 mess
MS has have seems to have caused some problems here. With:
  c:\> set PYLAUNCH_DEBUG=1 & py -3 -c "import os, sys; print(sys.prefix)"

I get:
   ...

   ("Systemet finner ikke angitt bane." == "File not found").

This is non-sense. I do have Python2 + 3 both on PATH (but both 32-bits).
Not sure if PyLauncher looks for 64-bit registry entries only.

But is there a way for py.exe to use '%USERPROFILE%\Local\py.ini' only?
I failed to find any good documentation on it's format.
