Modern Warfare 3 is a classic first-person shooter game that has been enjoyed by many gamers over the years.
However, some players have been experiencing issues with the game’s campaign mode not launching on Steam and Battle.net.
This can be frustrating for players who are eager to dive into the game’s immersive storyline.
In this article, we will provide possible fixes and reasons for the “Not launching on Steam and Battle.net” error.
How To Fix Modern Warfare 3 Campaign Not Launching?
1. Verify Game Files
The campaign may not be launching on your system because of a few corrupt files in your installation directory.
To solve this issue, head into Steam or Battle.net, based on which client you bought the Call of Duty title on. Then, select the game and choose the “Scan and fix” or “Verify file integrity” option.
This will scan your game files and replace any missing or corrupt files. This is a quick and easy fix that can solve the issue without having to reinstall the entire game.
2. Run As Administrator
Sometimes, the game may not have the necessary permissions to launch. To fix this, right-click on the game’s shortcut (on Steam or Battle.net) and choose “Run as Administrator.” This will give the game the necessary permissions to launch.
3. Update Graphics Drivers
Outdated graphics drivers can cause issues with launching the game. Make sure your graphics drivers are up to date by visiting the manufacturer’s website and downloading the latest version.
This will ensure that your system is capable of running the game without any issues.
4. Disable Antivirus Software
Antivirus software can sometimes interfere with the game’s launch process. Try disabling your antivirus software temporarily and launching the game.
If the game launches successfully, you may need to add an exception for the game in your antivirus software settings.
5. Reinstall The Game
If none of the above steps work, consider uninstalling and reinstalling the game. This will ensure that all game files are fresh and up to date. However, this is a time-consuming process, so make sure to try the other fixes first.
