If i ensured that dinput8.dll and scripthook installed in my steam game roots folder.

What version of Microsoft Visual C++ redistributables. Will do?

And how do you make sure that scripthookvdotnet net loads for the first time?

I forgot to explain how i got mods installed.
I put the Scripthook, Trainer and Ambiance files into my in game root folders. I used the OpenIV 2.9 ASI loader.

I just bought the game so i don't know if i am installing it properly. I need a simple explanation as much as possible.

I followed 2 years old youtube vids about installing OpenIV and mod essentials. But i can't get them to work (Like i pressed F4 F9 for Trainer / Ambiance yet it doesn't show any menu on singleplayer)

Mods i want it to get working and tools i used so far.
-Ambiance 1.1
-Script Hook V + Native Trainer 1.0.1103.2
-Open IV 2.9

I also am curious. Are those mods on the list works in the Director mod as well? In case that you want to use it with your GTA online character.
