When trying to use Legendary, I noticed that it didn't work on 7 because the latest releases use Python 3.9, it has the api-ms-win-core-path-l1-1-0.dll error.

To solve this, grab api-ms-win-core-path-HACK, and copy the x64 dll into %windir%\System32, and then copy the x86 dll to %windir%\syswow64.

Due to the way Legendary works, it extracts a minified Python 3.9 into %temp%, then it executes the code, because using an actually good coding language is too hard I guess. This means that the dll can't be used unless it is copied to the system folders. This probably works for more applications, I just don't know much that uses anything past 3.8.

I tested this with the latest Python 3.11 (portable ofc) and it works with that, so this will work for a lot of applications for the foreseeable future.

There is also this project which supplies Python 3.9 to 3.11 installers that support Windows 7 and Windows Server 2008 R2, basically by including api-ms-win-core-path-HACK and modifying the installers.

I'd think it would be better to just remove the requirement instead of including the dll if you're already modifying source.

Im an MSYS2 user (basically the current incarnation of a mingw based toolchain) and up to python 3.10 their builds support windows 7 https://github.com/msys2/MINGW-packages/blob/234364f40842c00e1bda49db3cf8496a7e4ba205/mingw-w64-python/0111-Add-support-for-Windows-7-Python-3.10.patch this version of python is quite different from MSVC built python.org python and on top of having several patches to support building it with a mingw/windows-gnu toolchain also has patches to adapt it to the several toolchains the MSYS2 project supports, it is however another python for windows 7 alternative.

Im currently still running python 3.10 however round when the last patch for clang 20 is available i may consider bothering with looking trough the msys2 python 3.11 codebase to see if i can remove those api-ms-path calls so it can run in windows 7, any other folks that could also be bothered would be much welcome

Python 3.9, 3.10, 3.11 and 3.12 for Windows Vista and 7:
