Oh actually I figured it out. It's CScenario Point Patch. I've ensured I was using the current version and I am. I'm not quite sure why this is causing an issue.

Yeah so I found out it's Scripthook V. I was using an outdated version. I updated it and installed it but still keep having issues. Everytime I install it and run GTAV the game still closes, it says Scripthook V needs to be updated even though it is. I would take out ScriotHook V and put it back in and run the game again, it still closes although it tells me now that the files need to be verified. I verify them and it goes back to saying Scripthook V needs to be updated. I've done this entire loop 4 times over.

I do have two copies of the game installed on separate hard drives, I'll uninstall the one I go online with and try that.

After much troubleshooting I've come to discover that the game would not start because of the dinput8.dll file. It's through steam, I open the game up and it does it's routine thing, checks social club and it loads up the R* Games launcher, however when it the game actually opens up it immediately closes.

It is 100% the file I mentioned because when I delete it, the game loads fine but when I add it back, it won't load. I tohught maybe it was corrupted and redownloaded the file like 8 times. Still no progress. Help?

Also yeah, there are no mods on the copy I am trying to load. The only modifications I made are the essential files I needed to start modding and are in the main directory. The mods folder is completely empty as well as the scripts folder.
