-Run game as Administrator.
-Case the mod menu don't appear after selecting it on the NIBMods menu, maybe its a issue related to the characters, suits or armors .ini files in Scripts\Characters (suits or armors) folder, delete all character .ini files from that folder and in game press Insert to reload scripts.
-You need internet access to login validation (if needed by mod)
Requirements to run my .net script mods in GTA V PC
1 - ASI Loader + ScripthookV by Alexander blade
2 - NIBSHDotNet
3 - Windows packages for NIBSHDotNet:
-Microsoft .NET Framework 4.5 (direct link)
-Microsoft .NET Framework 4.5.2 (direct link)
-Visual C++ Redistributable Package for Visual Studio 2013 (x64) (direct link)
-Visual C++ Redistributable for Visual Studio 2015 (x64) (direct link)
*You may need to uninstall newer versions of framework to be able to install 4.5. Remember to reinstall newer versions after install 4.5 (in this specific case).
**In Windows 8 or Windows 10 you may need to install some windows updates that will install the required packages + install the Visual C++ packs.
Scripts setup
Tip: You can use this guide as base for any V .NET script setup :) (for non .OIV packages)
Option 1: Simple setup (copy and paste)
Case the zip file don't contains a .OIV package file, you just need to extract the content of the ZIP to gta V Scripts folder, case the Scripts folder don't exists, create one.
Option 2: OpenIV package installer
Open OpenIV, select GTA V (Windows), in the menu Tools go to Package Installer, then select the .oiv file to open.
You will see a window similar to this one after loading, click in Install :)
Obs.: You also can open the .oiv file with winzip or winrar and extract the files from "content" folder to perform a manual setup.
Case the mod is not working a good thing to check is the .log files generated by ASI loader, ScripthookV and NIBSHDotNet, they may contain important info about what is failing.
Case you still have issues, check the troubleshooting:
