It’s a bit disappointing that the people who made the game haven’t given any official solutions or acknowledgments for the problem. But, let’s try to figure out why this is happening. One reason might be that the game can’t tell if there’s an update available. Also, if your internet isn’t working well, that can make the game stay stuck on the ‘Checking for Updates’ part.

Even though the game makers haven’t given us official help, there are some things you can try to fix the problem. In this discussion, we’ll talk about ways to fix MW3 Stuck On Checking For Updates Screen and get you back to enjoying MW3 without any issues.

Restart system

If you encounter this issue, another effective step you can take is to restart your computer. Sometimes, conflicts between different software can cause the problem you’re facing. By giving your system a fresh start with a restart, you might successfully resolve the issue and prevent it from happening again in the future.

Clear Cache and Temporary Files:

Accumulated cache and temporary files can sometimes interfere with the update process. To effectively tackle and overcome the persistent issue of being stuck on the “Checking for Updates” screen in COD MW3, a practical solution involves clearing out the game’s cache files. Follow these straightforward steps to address the problem:

  • Open Steam and navigate to your game library.
  • Right-click on Call of Duty: Modern Warfare 3 (COD MW3), select Manage, and then click on Browse Local Files. This action will take you to the directory where the game is installed.
  • Within the game’s installation directory, find the ‘mp23’ folder, and from there, access the ‘main’ folder.
  • Now, look for and delete the following files: cod23_data1.dcache, cod23_data0.dcache, cod23_toc1.dcache, and cod23_toc0.dcache.
  • With these cache files removed, launch the game again.

Verify Game Files:

Modern Warfare 3 may encounter update problems if some game files are corrupt or outdated. Verify the integrity of your game files through the game launcher or platform (Steam, Xbox, PlayStation). This will ensure that you have the latest and undamaged files. You can resolve this by repairing the files through the following process:

For Steam users, follow these steps:

1. Go to the Steam Library and right-click on COD MW3.
2. Select Properties and go to the Installed Files tab.
3. Click on ‘Verify integrity of game files.’
4. Once the verification is done, restart the game.

If you’re using, here’s what you need to do:

1. Open the launcher and find COD MW3 in the list of games.
2. Select ‘Options’ and then choose ‘Scan and Repair.’
3. After the scan is complete, launch the game and see if the problem persists.

Update the Game Manually:

If your game isn’t updating automatically, you can update it yourself. Just go to the official Call of Duty website or your gaming platform’s store. Look for the latest updates there and download them. Then, you can install them on your own. Doing this helps you keep your game current with the newest improvements and fixes. It makes your gaming experience better and more enjoyable.

Turn Off Firewalls and Antivirus:

Sometimes, extra cautious firewalls or antivirus programs can mistakenly think that the game update is something harmful. To tackle this, try turning off these security features temporarily while you update MW3. Don’t forget to switch them back on once the update is complete. This simple step can ensure a smoother updating process for your game without any unnecessary interruptions from security measures.

Check Your Internet Connection:

Make sure your internet connection is strong to help fix this issue. An unstable connection can slow down the game’s update check. Try restarting your router or connecting to a different network to improve your connection. Doing these things can make the game’s update check work better.

Get Rid of VPNs:

If you’re using a VPN, it’s a good idea to turn it off. VPNs can sometimes make it hard for the game to connect smoothly to the servers. By switching off the VPN, you avoid potential issues that could disrupt your connection to the game servers. This simple step of turning off the VPN helps make your gaming experience smoother and more enjoyable. Without VPN-related problems, you can stay connected to the game without any interruptions, letting you fully enjoy the gaming world without worrying about connection issues.

Server Status Check:

It’s a good idea to verify the current status of the official Call of Duty servers. If the servers are undergoing maintenance or are temporarily down, that could be the cause of the update problems. In situations like these, the best approach is to remain patient and wait for the servers to stabilize. Sometimes, these downtimes are temporary, and once the servers are back up and running smoothly, you should be able to proceed with the updates without any issues. If you’re having trouble with updates, the best thing to do is to check the Call of Duty server status. If the servers are down or being worked on, it could be causing the update issues. Just be patient and wait for the servers to get back to normal. Sometimes, you might need to give it a bit of time, and things should work smoothly once the servers are all good again.
