added the comment:
That's why I suggest using the launcher rather than absolute paths - there are far too many variations to enumerate with absolue paths (you didn't mention per-user Python 3.6 installations, for example).
If you have a suggested wording that you feel would explain things better, feel free to propose it. What's there at the moment seems relatively OK to me (aside from a minor tweak to use the launcher) so I'm not sure I could modify it in a way that would address your concerns.
