I'd like to know as well, my game has been working fine with a lot of add on cars. After the 1.0.877.1 update and the ScripthookV updated to the latest one. I can't spawn any of the added cars any more, all are invalid.
The old path (GTA V/update/x64/dlcpacks) and I copied everything there to GTA V/mods/update/x64/dlcpacks and it still wouldn't spawn. Anyone know why? Any fix?
I have been troubled trying to find out why none of my car mods have worked. Can someone give me a suggestion on how to fix this?? Or a list of all the files needed to run car mods? I have open.iv, i follow the instructions, I have dinput8.dll (most recent: 1.0.877.1) I have ScriptHookV (also most recent, finally). I honestly do not know what to do other than ask someone who is smarter than me lmaoo.
