Fatal upon launch?

I just downloaded five reborn and followed the instructions to the letter and when I went to start it up, this showed. The weird thing is that I had to reinstall it three times already and it has worked before this.What is going on?

Might wanna make sure you dont have LSPDFR or any other mods installed into your GTA V directory

Seems like he does have 'em. Look at the RPH shortcut on his desktop.

In my experience if you have any mods in your gta v directory it usually wont work, unless theres a different method im not aware of

I do have mods but they are mostly police car mods, car skins and come radio callouts

FiveM requires stock GTAV (unmodified, unedited) in order to work properly. Remove all mods, scripts, vehicles, ect, ect. and try again.
