The py.exe launcher cannot locate installations from the Store (unless you have no other installations on your machine, which is unlikely).

I added an "exe_display" override for listing paths, since the full path to the store app is not supposed to be used by users (it's different from sys.executable) and is only going to work when the shorter name is on PATH anyway (due to a limitation in Windows that I'm still trying to get fixed).

I also enabled support for the ExecutablePath key, which has the added benefit of making the debug py_d.exe able to find release Python 3.5+ installs (as well as finding the Store install at all, which is now using python3.8.exe as the main file because of the limitation I mentioned above).

MAX_VERSION_SIZE was increased, so the INSTALLED_PYTHON version string is now the full registry key name with the "-32" suffix. If that's intentional, you'll have to account for it in show_python_list. But I don't think the "-32" suffix belongs in the version string.

Ah, good catch, I didn't notice that.

Because those are special cases, we should strip it off the version string. One day when we implement PEP 514 properly then they'll come back (and we'll probably drop the -64 suffix for consistency with the PEP).
