I don't really get it honsetly, I have many vehicle mods I think that my friend got it for me and its not suppose to make any issue because I used to old LCPDFR and it worked fine now I tried to Install the new one and launch IV everything went fine till I saw Niko and saw on the left-top "ERROR.SCRIPT.LCPDFR.LOADER"
something like that, then I deleted that script and launched IV once again and it said nothing on the top-left but I clicked ALT+P and the LCPDFR not working now I read the guide of the manually installation and did everything like that even downloaded those things from microsoft even I got them tough as I know.
and now I tried to launch IV once again and it doesn't even work.
What am I suppose to do?
