For some reason they have the game files all hosted off platform at other hosts, so you can't install the game from the itchi.io installer you have to go to the third party websistes and download it there
Thank you, but I'm having a new issue. After that, I tried a third-party download, but I couldn't run the game after unzipping it. In detail, nothing happens after running the app: the game doesn't run, there are no error alerts, the game doesn't start in compatibility mode, and it doesn't start in admin mode. Can you help me, bro？
