When I installed Python 3.4, I included the py.exe launcher. I have just installed Python 3.5a0, then uninstalled it again, and the py.exe launcher has gone.

Either the 3.5 installer should notice that py.exe is already present and remember *not* to uninstall it, or it should warn the user when installing that continuing will take ownership of the launcher from a previous installation.

(I understand why having the same file owned by 2 installers causes problems, and that there's no easy fix, but the current behaviour is not at all friendly - I now have to reinstall Python 3.4 to fix it, or at least re-download the installer and try a repair, which might work I guess).

This is already fixed for 3.5 and later, since the launcher now has a consistent component ID regardless of which version/architecture of Python is installed.

It's too late to go back and make equivalent changes to the installer for 3.4 - running a Repair on a 3.4 installation is the best way to get it back.
