The program should be guiding you throughout most of the process. If things aren't obvious to you or you are getting error messages that you can't make sense of, please ask in the discord. You may also try enabling legacy auth within the programs settings should it not work naturally. Make sure you have auto updating disabled in Steam or Rockstar launcher, depending on which retailer you own the game on.

Make sure to import your ingame-settings to the newly created p127 profile folder. This is also an option within the program.
