Fixes for the ‘Join failed because you are on a different version’ error in MW3
The error may occur when attempting to connect to an online server or a friend’s server within the game.
Multiple factors can lead to encountering the “Join failed because you are on a different version” problem. Below are some potential causes:
- MW3 is not updated to the latest version.
- Local files are not in sync with the server.
- Your game version doesn’t match with your peers.
Now, here are some fixes you can apply to solve the error:
- Make sure to keep your game updated: Activision occasionally releases minor updates that might not automatically apply to your game. Therefore, regularly check for updates and install them. You can prompt the game to search for updates manually. On PlayStation, navigate to the system or in-game menu for updates. Xbox users can access updates by selecting “manage game” and then the update menu.
- Restart Modern Warfare 3: Sometimes, a hard restart can resolve various issues. Close Modern Warfare 3 entirely to ensure it’s not running in the background, then relaunch the game. Optionally, consider restarting your device as well. This action prompts the game to synchronize data and potentially resolve the issue.
- Encourage teammates to update: If your setup seems flawless, request your friends to verify their game version and perform any necessary updates. Ensuring everyone’s game is up to date can prevent compatibility issues.
