Are you having trouble playing Modern Warfare 2 or Warzone 2 due to the error code 2901? This error code can be extremely frustrating, but luckily there are a few steps you can take to fix the issue.

Error Code 2901 is an indication that your game is not running properly and that something is preventing it from functioning correctly. This can be caused by a few different things, including outdated drivers, corrupted files, or an outdated version of the game.

In order to fix the problem, you’ll need to address each of these potential causes in turn. We’ll be discussing the steps you can take to do this in detail below. 

Steps to Fix Error Code 2901 

  • Update Modern Warfare 2 and Warzone 2 to the Latest Version: The first step to take when trying to fix Error Code 2901 is to update the game itself to the latest version. This can be done by launching the game and then navigating to the “Options” menu. From there, you can select the “Updates” option and then click “Check for Updates”. If there is a new version of the game available, you can download it and install it in order to update the game. Once the update is complete, you should be able to launch and play the game without the error code 2901 appearing. 
  • Update Your Drivers: Another potential cause of Error Code 2901 is outdated drivers. Drivers are small pieces of software that allow your computer to communicate with the various hardware components in your system. If the drivers on your system are outdated, they may be causing conflicts with the game, resulting in the error code appearing. To fix this, you’ll need to update the drivers on your system. This can be done by downloading the latest drivers from the manufacturer’s website and then installing them. 
  • Verify Your Game Cache: If updating the drivers on your system doesn’t fix the problem, you may need to check your game cache. A game cache is a collection of files that the game uses to store information about your progress. If any of these files become corrupted or missing, it can cause the game to become unstable and the error code to appear. To fix this, you’ll need to verify the game cache. This can be done by launching the game and then navigating to the “Options” menu. From there, you can select the “Verify Cache” option and then click “Verify”. 
  • Reinstall the Game: If verifying the game cache doesn’t fix the issue, you may need to reinstall the game. This process can help to ensure that all of the game’s files are in the correct place and that they’re the correct versions. To do this, you’ll need to uninstall the game and then download and install it again. Once the reinstallation is complete, you should be able to launch and play the game without the error code 2901 appearing. 
  • Contact Activision Support: If none of the steps above have worked to fix the problem, you may need to contact Activision Support for further assistance. They may be able to provide additional help or advice in order to get the game running properly again. 


In conclusion, error code 2901 is a common problem encountered by players of the popular Call of Duty game series, Modern Warfare 2 and Warzone 2. Fortunately, the problem can be fixed by following the steps outlined in this blog post. We recommend that you update your game and drivers, verify your game cache and reinstall the game if necessary. If you’re still having issues, contact Activision Support for further assistance.
