All you have to do is download, unzip, and click the application.
Unless of course YOU have certain safety settings within Windows 11 enabled, in which case youll also get a pop up with something like "application from an unknown publisher" on it. Click more info and then run anyways. The game should run.
I'd be happy to help further if you still have issues but lose the attitude. It's not the games or creators fault you don't know how windows works.
