tsalgadot the exes are provided by Plutonium you don't need to touch it. The only thing to do is follow what the install guide says. Start the launcher, click Setup, choose the game that contains your game files then click Play. FYI the game exes are in %localappdata%\Plutonium\games but again you don't need to open/move them or do anything with them they'll be automatically used by the launcher when clicking Play in the launcher.
