I. Fix ERR_GEN_INVALID error in GTA 5 game

ERR_GEN_INVALID : Corrupt game data. Please reboot, verify the game data, or reinstall the game. For more information, please visit https://rgs.ms/verify.

This error message window appears when I just open the GTA 5 game for about 2-3 seconds, then the game will freeze and will no longer load, whether you press the OK button or not.

If you click OK to close the error message, the game will automatically close immediately afterwards.

This is an error where GTA 5 cannot retrieve data from the hard drive, specifically due to files RPF (RAGE Package File) of GTA 5 has been edited or deleted, and by default the game cannot run with the edited RPF files => ERR_GEN_INVALID error appears.

The main reason for file RPF Edited because we mod the game, mod vehicles, mod GTA 5 characters, install Vietnamese version of GTA 5,…

In case of RPF files being deleted, it rarely happens and the fix is ​​generally quite easy for copyrighted games, but for “pill” version games, you will almost certainly have to decide to install or redownload the game. Stop :((

Of course, the reason I encountered this error was because the RPF file was edited because of installing mods, but I will still guide you to fix the error in case the game is not modded at all, or the RPF file is deleted.

To mod the game, we definitely have to edit and add or remove a few files in the file RPF this is inevitable.

In addition, as I said above, because the default GTA 5 game will not run with edited RPF files, we have to install 2 additional OpenIV plugins: ASI Loader.asi and OpenIV.asi .

However, for some reason you have to remove these two plugins, but then forget to reinstall them. For example, if you uninstall it to be able to play GTA 5 Online, that’s the same for me 🙂

+ Step 1: In this case, the way to fix the error is very simple, just open the software OpenIV up => and select Windows in the Grand Theft Auto section.

Then click Tool => ASI Manager to open OpenIV’s included ASI plugin management tool as shown below.

+ Step 2: Then, you proceed to install 2 plugins ASI Loader and OpenIV.ASI when the background changes from blue to green as shown below, it’s OK. And as you can see in the description of OpenIV.ASI :

This ASI Plugin allows your game to load with modified RPF archives. It also provides support for “mods” folder – That is This plugin will help GTA V work normally with modified RPF files (mod)…
