Custom Mod Manager (IV) - a program with which you can not change the main system files of the game, which are usually edited when installing mods.
That is, you can create a “BMWX5” folder in the “mods” folder by dropping the appropriate files there that are needed for the correct display and behavior of the model (carcols, handling, vehicles, etc.). Next, run the Custom Mod Manager, select the "BMWX5" line, start - and that's it, in our game the appropriate settings (files) for the BMW X5 mod are loaded.
Running a regular GTAIV.exe will launch a clean game.
Works great on patch 1.0.7.0, performance is not guaranteed on others.
.Net Framework 3.0 is required to run the program.
