I'm trying to use a game mod manager called XXMI Launcher: https://github.com/SpectrumQT/XXMI-Launcher

Attempting to use the portable version or the .msi installer results the same error: "procedure entry point PssQuerySnapshot could not be located in the dynamic link library C:\Users[username]\Desktop\XXMI\Resources\Bin\python313.dll."

x64dbg log:

Okay, PssQuerySnapshot is first introduced in Windows 8.1. So I run the program again with VxKex-NEXT installed. Windows no longer displays an error but the application will not open. x64dbg doesn't show any exceptions like before.

Alternatively, I try replacing the included python files with a version of patched 3.13.12 (https://github.com/adang1345/PythonVista) without running VxKex-NEXT. The result is the same, Windows no longer displays an error but the application will not open. x64dbg doesn't show any exceptions.

Any ideas? It seems like the dlls are loaded but nothing happens. If you can XXMI Launcher on Windows 7 or 8 let me know. Thanks.
