[issue24306] Backport py.exe to 3.4

[Steve Dower]

Steve Dower added the comment:

Attached a patch to set the component IDs in the 3.4 installer to match the ones we're using for 3.5 and later. This should prevent downgrading of the launcher in future releases, though it's not strictly the "right" way to do this. (Nosied Martin in case he wants to weigh in on this.) (The right way is to have a separate MSI with a matching upgrade code, which is not feasible for 3.4.)

Unfortunately, it won't help when 3.5 is installed per-user (the default), but there's nothing we can do there short of backporting the launcher changes, probably selectively to avoid the fixes for the VC10->14 change. (Nosied Larry to see if he wants to approve this.)
