Ok well I removed the faulty RAM stick and reinstalled windows and all its updates along with service pack 1. (Previously updates and service pack 1 wouldn’t install correctly or not at all due to the faulty RAM stick) Downloaded the launcher and editor and everything works fine now, so if anyone else is having weird issues with installing not just unreal but windows updates including visual download “memtest86+” and run it make sure it doesn’t detect any errors. Big thank you to everyone who gave suggestions and happy developing.
