Yea batch file would be best there for sure. I don't intend on cheating Online. Just have a simple case of already having an installed cracked GTA version 2802 which doesn't use the main usual Documents\Rockstar Games folder for Social Club etc at all & has its own folder for settings & saves etc. I just thought it would of been simple to just update that 2802 to the latest 2845 & use that for mods, don't care for Online play for that copy. Can't find a cracked 2845.
Thanks for the info!
