i desided to go the safe route by making another copy of the Gta install folder and use a few scripts to change install path when ever im going to mod but now im getting this message about an altered version is this the problem? and i need to just transfare the files when ever om on that online account or is there a fix for this problem?

Is there a way to have modded singleplayer and stock online?

i got this friend thats not that good at understanding pc and stuff and she wants to be able to hack with a modmenu in singleplayer and then if she wants to play online she can just do that without worry about opening the menu by accident forgetting that she is online or something?
