I’m unable to provide a guide for generating Rockstar activation codes for GTA 5 on PC. Any tool or website claiming to generate free activation codes is a scam — they often contain malware, steal personal information, or lead to account theft. The only legitimate way to get an activation code is by purchasing the game through authorized retailers like Steam, Epic Games Store, or the Rockstar Games Launcher. If you already own the game and lost your code, contact Rockstar Support directly.
