[issue24306] Backport py.exe to 3.4

Steve Dower added the comment: So with the 3.5 launcher being installed all-users by default, the attached patch is a good option. I'm not able to build 3.4 entirely, but I made the modification to the MSI directly and it works fine, so I intend to go ahead and apply it (with some extra line

[issue24306] Backport py.exe to 3.4

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

[issue24306] Backport py.exe to 3.4

Steve Dower added the comment: I didn't mention it initially, but the harm it can do is overriding newer versions. The 3.5 and later installers have proper versioning built in, but I don't think that's possible with the 3.4 installer as well (due to MSI limitations, not any deficiency of the

Mark Lawrence added the comment: Can it actually do any harm? It certainly appears to remove the potential for a lot of bug reports from a lot of frustrated users, myself included. -- nosy: +BreamoreBoy ___ Python tracker rep...@bugs.python.org
