Why Can't I play F1-24, and show me an Anti-Cheater message?

@Manquip Yes, for better or worse this year's game includes EA Anti-Cheat. Unfortunately, sometimes anti-cheat programs will flag perfectly normal programs that have nothing to do with the game as "cheats" and prevent you from running the game.

Turning off or uninstalling conflicting software can help you get back in the game.
