How to Fix Can’t Launch Bug

It’s not uncommon for bugs and issues to pop up in the Call of Duty franchise. CoD MW3 is newly launched, so it’s sure to have its share of errors and bugs. Most notably, players have been struggling to launch the game, which is among the most frustrating issues to come across. Here’s what you can do.

Check Activision Server Status

When in doubt, check the server status first. Taking a look at the servers will give you a heads-up if the game is undergoing any maintenance that could be causing the bug.

Verify File Integrity

Game crashes and a failure to launch are often time linked to issues in the game’s installation files. So, you’ll want to verify your files to ensure this isn’t the root of the problem. Here’s how to do it.

  • Steam Client
    • Steam > Library > Right-click CoD MW3 > Properties > Local Files > Verify Integrity of Game Cache > Wait for the scan to complete.
  • Battle.net Client
    • Battle.net client > Right-click CoD MW3 > Scan and Repair (Verify Files in Local Drive) > Wait for the scan to complete.

Run Application as an Administrator

Oftentimes, you’ll need to run the application as an admin on your PC. I recommend you try it out for Steam, Battle.net or CoD MW3. Here’s how to do it.

  • Right-click the application shortcut > Run as Administrator.

Update your GPU

Occasionally,  the issue arises from your Graphics Drivers being out of date. So, it’s best to check for any necessary updates. Here’s how to do it.

  • For Nvidia Graphics Drivers:
    • Go to the official site and download the drivers.
    • Once the download is complete, select the download file to initiate installation.
    • Restart your PC after the download is complete.
  • For AMD Users:
    • Open Device Manager by pressing Windows and X and find out Device Manager.
    • Display Adapters > double-click it.
    • Right-click your AMD video card driver 
    • Select Update driver.
    • Select Search automatically for updated driver software, and you will see if there are any updates to apply.
