Am I the only one with this problem with trying to run the game?

I’m not sure if this is the right subreddit to ask, but the Unleashed Recomp doesn’t seem to open whenever I try to run it. No matter how many times I click it. Even if I download a new one, it just doesn’t run. It’s like the only one that I need to download this game. It’s where it’s supposed to install the files before it can download the whole game.
