You have to create a separate user on your PC without microsoft account. Make sure it has a password. Afterwards, follow the steps:

  1. Open the cmd with administrator rights
  2. Write in next command /user:(USERNAME) “(LOCATION OF LAUNCHER.EXE)”
    For example, for me it was /user:redm “D:\Software\Rockstar\Launcher.exe”
    Make sure to insert a space before /user:…
  3. It will ask you to write your password. If you try to write it and the signs don’t appear in the cmd as you write - Don’t Worry, It should be like that. Just write your password once it asked you - don’t click on anything, JUST write the password using your keyboard. Afterwards press Enter.
  4. The Rockstar Game Launcher will be launched. You will be able to write your email and password and log-in.
  5. After you logged-in launch Epic Games or Steam without administrator rights (do everything, except cmd, without administrator rights).
  6. After it got launched, launch RedM - everything will be launched!

To launch a game, for example tomorrow, you have to launch the rockstar game launcher from the cmd. I recommend to copy the command into a text file and paste it each time.

Good luck, if you have troubles - write here!
