Modern Warfare 3, the third installment in the popular Call of Duty series, was released in 2011 and has been a fan favorite ever since. However, some players have reported issues with the game not launching, which can be incredibly frustrating. If you're experiencing this problem, don't worry – there are steps you can take to fix it and get back to playing the game you love.

1. Check your system requirements

First and foremost, make sure your computer meets the minimum system requirements for the game. Modern Warfare 3 requires a 64-bit operating system with Windows 10 and a 64-bit processor. It also recommends an Intel Core™ i5-6600 or AMD Ryzen™ 5 1400 processor. If your computer falls short of these requirements, you may experience issues with the game not launching.

2. Update your graphics card driver

One common cause of games not launching is outdated graphics card drivers. Make sure you have the latest driver installed for your graphics card. You can download the latest driver from the manufacturer's website or use software such as Nvidia Geforce Experience or AMD Adrenalin to update your driver.

3. Whitelist the game in Windows Firewall

Antivirus or firewall software may sometimes block the game from launching. To prevent this, you can whitelist the MW3.exe file in your Windows Firewall. This will allow the game to communicate with your computer without interference from your security software.

4. Allow access when launching the game for the first time

When launching the game for the first time, you may be prompted to allow access for the game to communicate with your computer. Make sure to click “Allow” to prevent any issues with the game launching.

5. Disable overclocking and performance-enhancing programs

Overclocking and performance-enhancing programs, such as iCUE, Razer Synapse, and Armory Crate, may cause instability and prevent the game from launching. Try disabling these programs before launching the game.

6. Repair game files

If the game still won't launch, you may have some damaged or corrupted game files. You can repair these files using the Battle.net Launcher or Steam. For Battle.net users, click on the Modern Warfare icon, click on the Gear Button, and select “Scan and Repair” to scan for any broken or corrupted files. For Steam users, right-click on Modern Warfare 3 in your Library, select Properties, and click on the Local Files tab > the Verify Integrity of Game Files button.

7. Update your operating system and graphics card driver

Make sure your Windows operating system and graphics card driver are up to date. Outdated software can sometimes cause issues with games not launching.

8. Disable fullscreen optimization

Some players have reported that disabling fullscreen optimization can fix the issue of the game not launching. To do this, go to the game's installation folder, right-click on the MW3.exe file, select Properties, and check the box next to “Disable fullscreen optimizations” under the Compatibility tab.

9. Run the game as an administrator

Running the game as an administrator can sometimes fix launch issues. Right-click on the MW3.exe file and select “Run as administrator”.

10. Check for conflicting software or hardware

Some background programs or devices may interfere with the game's launch. Try disabling any controllers, virtual reality headsets, or other devices and programs that may be running in the background.

11. Reinstall the game

If none of the above steps work, it's possible that some game files may have been corrupted or missing during the initial installation. Try reinstalling the game to see if this resolves the issue.

12. Contact Activision Support

If you've tried all of the above steps and the game still won't launch, it's possible that there may be a larger issue with the game itself. In this case, contacting Activision Support may provide more specific solutions or troubleshooting steps to fix the issue.
