Ive recently come to the conclusion that i would like to have custom vehicles in my LSPDFR game, so i come to this website and find some i like but after the download is complete and i go to open it, the message "this file does not have an app associated with it to preform this action"? Im running GTAV from the rockstar launcher (not the steam version) and this happens for some plugins as well. I've managed to download the assorted callout plugin and protection squad without any trouble, but some other things do not work. Have searched for solution's but haven't found one? help?
