Bugs and errors are some of the most frustrating yet unavoidable aspects of gaming. Unfortunately, even triple-A titles with huge developer teams won’t be glitch-proof.

Dev Error 6068 is one of the most common errors plaguing Call of Duty players. The error may be caused by multiple things, including a corrupt DirectX installation, outdated or corrupt Windows files, outdated or corrupt drivers, and corrupt game files.

    Force Run with DirectX 11

    Many games do not run properly on the newer DirectX 12. This may be the case for Dev Error 6068. However, some games seem to run better using the previous version DirectX 11. To force Call of Duty to run with DirectX11, follow these steps. 

    1. Open the Battle.net launcher
    2. Select Options, then Game Settings.

    2. Click Options and then Uninstall Game.
    1. Once the uninstallation completes, restart your PC. 
    2. Launch Battle.net again and select Install for Call of Duty: MW.

    Run SFC and DISM Commands

    Because the Modern Warfare Dev Error 6068 can be caused by corrupted or unstable Windows files, system repair tools can fix the error. These are the System File Checker (SFC) and the Deployment Image Servicing and Management (DISM) tools. Try running these tools to repair your Windows files, then restart the game. 

    Check Your RAM

    A common cause of Dev Error 6068 is incompatible or dysfunctional RAM. While it’s uncertain how your RAM can cause the issue, many users have claimed that installing newer RAM fixed their error. You can also diagnose and test your RAM to see if it’s functioning correctly. 

    If nothing else in this article works, you may wish to consider upgrading your RAM. We recommend only doing this as a last resort. 

    Back to the Gulag

    Hopefully, one of these fixes solved your Dev Error 6068 problem, and you can get back in the game. If they did, consider sharing the solution with Activision and the COD: MW community as this will help others fix their game, too. 

    If nothing worked, hopefully, the developers will work out the root cause of this error and release a patch that fixes it!
