Bug description:

Tested with Python 3.13b1 release.

Installed libraries:

CPython versions tested on:

3.13

Operating systems tested on:

Windows

That's actually a shockingly short list of libs in there... do you have log files handy? They'll be under %TEMP%\Python*.log, and the main one I'm interested in will end with dev (and probably be the latest date, in case you have multiple installs).

Here. Can provide other logs as needed.

I only have one install of 3.13 - I uninstalled and started from scratch for the sake of this issue.

Huh, no, it just looks like we've only ever shipped that few. I guess I'm so used to working with the Nuget packages that I had forgotten the MSI is more selective.

We should add the free-threaded libs to the old installer. We should also reduce the libs included in the other packages to avoid shipping too many files.
