Sometimes, this problem can also happen if the Battle.net client is currently updating on your PC—updates can interrupt the game from starting. In this article, we’ll walk you through several easy ways to fix this error.
1. Run COD MW/Warzone from the Installation Folder
In certain situations, the shortcut you use to launch the game may not point to the correct game file. If this happens, the game won’t start at all. Also, issues with the Battle.net client can prevent the game from starting correctly. To fix this, try running the game directly from its installation folder:
2. Run COD MW/Warzone as an Administrator
If the game doesn’t have the right permissions to run, it may not start. This can sometimes be caused by third-party security software or other programs blocking it.
3. Restart Your PC
Simple as it seems, restarting your computer can often fix unexpected errors. Sometimes, drivers or other system components aren’t working properly and need to be reset. Restarting your PC reloads everything and might solve the problem. If the error message still appears after a restart, continue to the next step.
4. Stop the Battle.net Update Process in Task Manager
If Battle.net is updating itself in the background, any games you try to launch through it may not start. You’ll need to stop the update process before you can play.
5. Delete Temporary Data Files
Sometimes, small data files or save files left over in the installation folder can cause problems if they become corrupted. These may be temporary files or crash reports. Removing these temporary files can often resolve the issue.
6. Clear the Battle.net Cache
Battle.net stores some temporary files (cache) to help it run smoother. But if these files get corrupted, it could prevent the game from launching. Deleting these files will force Battle.net to make new ones and can fix several issues.
7. Change the Game Region
If the region selected in the Battle.net client does not match the region you are actually playing from, you may experience problems. It’s always best to set your game region to where you really are.
8. Remove Command Line Options
Sometimes, custom launch options or command-line parameters entered in Battle.net can clash with the game and prevent it from starting. These are similar to launch options in Steam.
9. Repair the Game Files
If your game files are corrupt or missing, the game may not run as expected. Fortunately, Battle.net lets you check and repair these files easily.
10. Change the Installation Directory
The location where your game is installed can sometimes cause issues, especially if it’s not on your main system drive or not in the default path. To fix this, you may need to move the game to a different folder or even a different drive.
11. Reinstall Call of Duty MW/Warzone
If nothing else has worked, the issue may be deeply rooted in the game installation itself. In this case, uninstalling and reinstalling the game is often the best solution.
