[New-bugs-announce] [issue32730] Allow py launcher to launch other registered Pythons

New submission from Peter Suter <petsuter at gmail.com>:

For example Anaconda Python is registered under HKEY_LOCAL_MACHINE\Software\Python\ContinuumAnalytics\Anaconda36-64\ as described in PEP 514 "Python registration in the Windows registry" .

The py launcher from PEP 397 however ignores that and only considers HKEY_LOCAL_MACHINE\Software\Python\PythonCore\ registrations.

There seems to be no mechanism to register Anaconda Python with the py launcher. Anaconda considers this a bug in the Python launcher. https://github.com/ContinuumIO/anaconda-issues/issues/149#issuecomment-361922640

Shouldn't this be possible? Maybe via py.ini [defaults]?
