It may be that your copy of the launcher is a little old - some changes were pushed just yesterday (but I'm not sure if Vinay made a new installer yet). It has slightly better debug output (although generally not what you are asking for yet) and better "cross-bittedness" support.

Installed new version:

msiexec /i launchwin.amd64.msi ALLUSERS=1

Expected behaviors of registry changes occurred. Still launches python 2, though, whereas c:\windows\py.ini contains:

[defaults] python=3

[commands] /usr/bin/perl=C:\perl\bin\perl.exe

Here is the debug output. Seems like it isn't recognizing the python=3, even the new version.

So, looking at the code, get_configured_value produces that message, but there are 3 places to look for "python". Setting the environment variable makes it work. Eliminating the environment variable, I then copied c:\Windows\py.ini to c:\users\glenn\appdata\roaming\py.ini. That worked. So I guess the syntax of my py.ini file is correct. But apparently it isn't properly using c:\windows\py.ini !! Yet curiously, it reports the correct name for the global configuration file.

Aha!

Bad logic is get_configured_value! get_configured_value only looks in the global configuration file if there is a local configuration file that doesn't have the setting. It should look in the global configuration file if there is no local configuration file OR the is a local configuration file without the setting.

I'll await a new launcher.
