I’ve recently been playing GTA V mods on my PC and obviously I must have made some sort of mistake installing a certain file and I have currently have this “zlib” error. I am here to tell you how to fix this error if anyone else is having this issue.
If using the disc version, you can attempt to repair GTAV from the discs or by using the command line -verify(for more information on command lines, please see this Support article). If on Steam, you can try to verify game cache to fix the installation.
If the error still appears after trying those steps, or if you are using a digital version downloaded from Social Club, go to Add/Remove programs in your Windows Control Panel and uninstall GTAV. Then reinstall the game, either from the discs or by downloading directly from the Social Club GTAV Activation Page.
If anyone else is still having any issue don’t hesitate to drop me a tweet @GamerExGB
