Prerequisites: GTA V installed on a PC, and access to the folder containing the various elements of the game (which will be in a different location on your disk depending on whether you used a launcher like Epic Games, Steam or Rockstar, or if you directly downloaded the game (for example a cracked version)).
To be able to install and modify mods on GTA V for PC, you will need:
OpenIV
→ to explore the game files and extract/modify textures, models and .ytd / .gfx files. Download and install openIV via the following link (click on “Download now” then open the downloaded installation file, follow the instructions step by step and wait for the installation to complete) → https://openiv.com/.
Open openIV, select “GTA V” and carefully choose the “Windows” version, then indicate the path to the folder where the “GTA5” application file is located (the folder containing the game elements).
Open Open IV
Activate the “Edit Mode” at the top right
Create a backup of the original files in OpenIV: Tools → ASI Manager → Install “ASI Loader” and “OpenIV.ASI” → Close (to modify only copies of the original game files and thus be able to recover them if there is a problem)
In file explorer
Script Hook V to put in the root allows you to run custom scripts in GTA V.
→ Download link
Download the folder from the link, then open the archive
Go to the “bin” subfolder then select the “dinput8.dll” file and drag&drop it into the root of the game folder.
A Windows window opens and proposes to replace the “dinput8.dll” file because it already exists in the root → click on “Replace the file in the destination” or “Yes”
Then select the “ScriptHookV.dll” file and drag it into the root of the game folder as well
Script Hook V .NET (to put in the root)→ allows you to write scripts in C# (.NET)
→Download link
⚠️⚠️⚠️INSTALL THE “NIGHTLY BUILDS” ⚠️⚠️⚠️
Download the folder from the link, then open the archive (be sure to take the “ScriptHookVDotNet-v3.6.0-nightly.126” version)
Once in the folder, select the 7 files whose name starts with “ScriptHookVDotNet” (excluding the “Docs” and “Licenses” folders as well as the text file “README”) and drag them into the root of the game folder
Installation of the Trainer (external software or script that serves as a cheat menu and management: it allows you to instantly access, in real time, options that are normally impossible or limited in the game (unlimited money, weapons, vehicles, weather, teleportation, activation of mods, etc)
Open the following link, click on “Download” a first time, which will open another page, then a second time on this other page to start the download
→ Download link
Once the compressed folder downloaded, open it and select the last two files (named “TrainerV.asi” and “trainerv.ini”) then drag them into the root of the game folder
This tutorial is now complete! You now have all the basic elements necessary to install most mods for GTA V, and your game is properly configured. When you want to install a mod in the future, take the time to consult the description of it on the platform where you find it (for example GTA5-Mods.com) or the text file “readme” contained in its folder, if there is one. Indeed, some require the presence of other files or applications but don't panic, you will almost always find the necessary instructions to install your mod, and there will normally not be too complex manipulations. Thank you for following this guide to the end :)
