Many PC players are experiencing DirectX Fail error that prevents them from playing Modern Warfare 3. The game either stops running after a brief period or does not boot up at all, with a message that says that MW3’s DirectX has failed.

All MW3 DirectX error fixes

DirectX errors can occur when your device does not have the latest DirectX version installed, which can make the game or software you are trying to use incompatible. Here are some solutions to fix this issue:

• Restart your computer: Sometimes, unexpected bugs or system issues can cause DirectX errors in Modern Warfare 3. Restarting your computer may help resolve these issues.
• Verify game files: If the error persists, it's possible that Modern Warfare 3 files are corrupt. You can try verifying the integrity of the game files through the Steam or Battle.net launcher to repair any corrupted files.
• Update DirectX: Next, you want to make sure your DirectX is up-to-date with the game's requirements. You can check your DirectX version by typing "dxdiag" in the Run utility (Windows + R keys) and looking for the "DirectX Version" line under the System tab.
• Update software and drivers: Outdated software or drivers can also lead to DirectX errors. Make sure to update graphics drivers to the latest versions to prevent encountering DirectX errors. This method can also fix any crashing or performance issues in Modern Warfare 3.

• Reinstall DirectX runtimes: If you continue to experience DirectX errors, you can try reinstalling DirectX runtimes as an additional troubleshooting step.
• Check for missing DirectX files: If you receive an error message about missing DirectX files, you can download the DirectX installer from Microsoft's website or use the bundled DirectX installer that comes with Modern Warfare 3 to fix the issue.
• Reinstall Modern Warfare 3: If you have speedy internet, you can also give this a try — uninstall and reinstall Modern Warfare 3 and see if the DirectX error is fixed. This should be your last option, though, because you’ll have to go through the hassle of logging in again, agreeing to the terms and conditions, and setting up your preferences.
