@haws1290 how often does this happen. I've been playing this game for about 9 months now and this is the first time it's happened to me.

I just got the same error today, it was working two days ago. the error states Unknown game version then tells me what versions are supported, the version I currently have is included in that list so I'm not sure what the problem is.

I recently tried out GTA V Redux but didn't really like it, so I did what they said to uninstall it by deleting my Mods folder. I then created a new Mods folder, and copied Update, and X64 folder into it. And put all my old mods back into the folder. Everything was working fine and then I realized that some vehicles after spawning them disappeared after a few seconds. One car for example is the Ocelot Jugular, among about 7 or 8 other cars just in the Sports Car Category. Does anyone know how to fix this? I am using the latest version of Simple Trainer to spawn vehicles, and I am using the Steam version of GTA V.

@Hieix great thanx for the info. I'm going to check it right now. I'll update you once I get openiv reinstalled..

I am upgrading my mobo in a couple of days and along with that I'm doing a fresh install of Windows 10. I already have Open IV installed (on the drive I'm reinstalling Windows on) and I have all my mods in a mod folder (on a different drive, not the drive I'm installing Windows on) , but when I install the new mobo and reinstall Windows and OpenIV it's going to ask me if I want to create a mods folder for all mods, but since I have my steam games library on a separate drive along with my mods folder that I'm not wiping do I just say No when it asks, or am I going to have to create a new mods folder and move all my mods from the old mods folder to the new one? Any info would be appreciated guys, thank you.

So I've been out of town for a week, while i was gone it looks like ScriptHookV got an update, it informed me right when I booted up my computer and asked if I want to install. I said yes. So a couple hours later I go to play GTAV Single Player and I get a error: Fatal Unknown Game Version, check dev c for updates and a website to go to. So I went and downloaded the latest version of scripthookv, extracted it, replaced my old ScripHookV.dll file and dinput8.dll file then went to play the game and it crashes everytime I try to play it, it will just be getting into the game and then will crash. Also my OpenIV disappeared after I got that first error message. Can someone help me. I really hope I don't have to reinstall everything and lose all my mods and stuff.

@Reacon Ok, thanks after a few hiccups I got it to work. Thanks a ton.

@Reacon lol, thanks, i appreciate it

@Reacon Okay so I do have GTAV\mods\update\x64 but theres nothing in my x64 folder. I also have GTAV\mods\update\update.rpf and within that update.rpf folder is common, dlc_patch, and x64 but once again no dlcpacks folder in that x64 folder either. So am I just going to copy the update folder from the game folder and replace the mods update folder with that one? And if so once that is done can I then go ahead and delete the mods from the dlcpack game folder since they’ll be in the mod/dlcpacks folder. Sorry if I’m overthinking this, I just don’t want to mess up my game, and I’m pretty new to modding.
