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!
Unfortunately I am that slightest bit paranoid, but thanks for the heads up tip! I'll note that down, seems like a nice quick way. I've been banned before (not mods related) & losing the time invested & personal setups of dumb number of garages & cars, doing up cars, clothes, achievments, stats etc etc really traumatized me lol. Please understand my paranoid status.
I mean my ideal setup I wanted would of been 2 totally separate GTA installs/separate profiles, 1 my current legit GTA & other ofcourse for mods only/experimenting/strictly offline only without having to rename anything when choosing to play between single player mods or my legit GTA. Is that even possible? Would that mean I'd need a separate Social Club account for my single player mods GTA or do I even need a Social Club account for single player only??
All gotta start somewhere 
Thanks for your time.
Thanks for replying JohnFromGWN. I wasn't sure if I could just make a copy of my GTA, thought maybe profiles would conflict or some shit. I've just got waaaay too much time invested in my legit GTA since PS4 transfer, single & more importantly Online so I can't help but try be extra safe/peace of mind.
I'll use the 1st method you mentioned & just copy whole game folder & rename, plenty of space on my drive, all good.
Cheers.
Hi all.
I have a normal legit GTA installed, which ofcourse has the latest updates.
I also have another "copy" of GTA which I'll be using for just single player mods & experimenting etc. But for this I can only find GTA V copy with older game version/update of 2802 & not the latest 2845.
Is there a way to update my GTA V single player version from 2802 to 2845? Can I use files from my current legit 2845 GTA to update my other 2802 GTA ?
Thanks.
