Troubleshooting
- The launcher says this GTA V build is not supported
- If your game is newer, Rockstar has updated it: keep it and update next:mp when a release supports the new build. If it is older, update the game through your store.
- The launcher reports damaged or missing files
- Press Repair. Antivirus software sometimes removes nextmp-client.dll; add the next:mp folder to its exceptions if it happens again.
- GTA V starts but next:mp does not appear
- Restart the Rockstar Games Launcher (and Steam or Epic), start story mode once, then try again from nextmp.exe. Antivirus software is a common cause; if it repeats, create a diagnostics file in the launcher.
