Gta V Rg Mechanics Size
Do you mean you had installed RG version and then AFTER trying to apply Reloaded crack you get that error?if yes-After installing RGmech release i have installed social club from redist folder that came with installation files from torrent.here i played for 10+ hours, lots of crashes.Then i applied crack files from Reloaded that were in 'Crack.RLD' and 'GTAV.Retail.to.Steam' to the main RGmech installation directory. I didn't install SC from reloaded's 'installers' dir. It worked.Now that i look at Reloaded crack files i see an 'update' folder but i don't remember applying it. Try to not use it at first.if no-I can't help you much, the installation of RGmech was easy, it cracked itself.

Only thing i had to do additionaly was to instal Social Club from their redist folder. Without it the game always said my SC account is wrong or something.As for RGmech installation errors, i had one ISdone.dll error until i did free some more space. 150GB free space on installing partition and 6GB on sys parition worked for me.
