I can't find and chose version on installation option

I bought and installed the product normally. Later, I tried to start the game, but it didn't start because there was a problem with the setting. So I looked up and found that normal people should go into the installation settings and choose the installation version, but I can't. I don't know what the problem is. I deleted the game, downloaded it, tried Windows, and even deleted the game files one by one. No. Tell me what the problem is and how to solve it. I'm trying to play a game with Mac and I get the same result even if I try with Windows.
