from that window you can install ASI Loader and OpenIV. While in OpenIV, click on Tools and choose ASI Manager.
Right now it’s not necessary since we are planning to add scripts in this tutorial. You can add the Scripts folder in the same directory as the mods ( Main GTA 5 folder ). When you set up openIV it will likely ask you to create a ” mods ” folder in your game directory, But if it didn’t, just create it manually and It’ folder will automatically get a purple color. But with the “mods” folder you only need to restore a portion of GTA 5. you can install GTA 5 mods in the game folder too, but it’s not recommended at all since some mods can crash your game, and then you have to reinstall everything from beginning our restore your backup. In order to install GTA 5 mods, you need to have a mods folder in your GTA 5 directory. You have to enable “Edit mode” in order to edit game files with OpenIV.
Of course your files are different from what is shown here, because this GTAV is already modded.
