Python 3.13 b1 x64 Windows Installer problems

[ThomasGessert]

Bug report

Bug description:

I tried the installer on two Win11 Pro systems (23H2, 24H2 beta), upgrade from a6 and fresh install. On both systems pip was broken afterwards.

Error message:
"no module named pip"

On the 24H2 system additionally the "scripts" folder got deleted while upgrading. The a6 installer works fine.

CPython versions tested on:

3.13

Operating systems tested on:

Windows

Are you using a non-English version of Windows? There is a known issue causing pip to fail.

[ThomasGessert]

Yes, I'm on a german windows. Probably its worth to mention that I did an all-user installation with precompile standard lib option.

Normally it's worth mentioning, except we know this will be the same issue as #118773. It's fixed for the next release.

Until then, if you disable pip then it should install, and you can patch your own tempfile.py to remove the mode=0o700 argument from any mkdir calls. I understand that's enough to get pip to run.
