I think, that it cannot be even launched as I know, on website https://gsak.net/index.php is written that it is supported Windows 7, Windows 8, Windows 10, with XP and below not supported. So I understand it like this. But I think that it is possible to launch and run without any difficulties. But be careful. But I am glad that you are giving questions like this. I would also like to launch it on Windows 11.
