I give up. Thanks for trying to help me
The demo was fun
Aw - I did fail to mention the official Itch app - https://itch.io/app - if you aren't using it, try it that way, i think it might be your best chance.
If that doesn't work, lastly, if you don't play games often etc, the other thing that might be out of date on your computer could be https://aka.ms/vs/17/release/vc_redist.x64.exe (from https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=ms...) - outside of that, antivirus or soemthing with your computer set-up, so try it on a different Windows 10/11 machine.
