The fact is that the game is updated and accordingly mods are made for certain updates that you may not have. If you downloaded a mod and the installer refused to install it in your game, be sure to check whether all the add-ons, or as they are also called DLC you have installed. I will answer this question once and here.
I see a frequent question in the comments about an error that occurs at the beginning of installing some mods in the game. Installing any other mods is no different from what we did before. Now you can safely download from our site: cars, motorcycles, scripts and everything That you will like.
Start the game and if you installed everything correctly, the game should work without any problems.
