Error 6345 is a common issue faced by gamers playing Warzone and Modern Warfare. This error can be frustrating as it disrupts the gameplay and prevents you from fully enjoying the experience. In this blog post, we will explore various methods to fix Error 6345 and ensure uninterrupted gameplay. By following these steps, you'll be well on your way to resolving this issue and getting back into the action-packed world of Warzone and Modern Warfare.

Close Background Apps


One of the main reasons for Error 6345 is having too many background apps running simultaneously. These apps can consume valuable system resources and conflict with the game. To fix this issue, follow these simple steps:
  • 1. Press Ctrl + Shift + Esc to open the Task Manager.
  • 2. In the Processes tab, identify any unnecessary apps or processes that are running in the background.
  • 3. Right-click on the app or process you wish to close and select "End Task".
  • 4. Repeat this process for all unnecessary apps or processes.

By closing unnecessary background apps, you'll free up system resources and give Warzone and Modern Warfare a better chance to run smoothly.

Verify Game Files


Verifying game files is an essential step in identifying and fixing any corrupted or missing files that may be causing Error 6345. Here's how you can verify game files within the Battle.net client:
  • 1. Launch the Battle.net client and navigate to the Games tab.
  • 2. Locate and click on Warzone or Modern Warfare from the list of installed games.
  • 3. Click on the Options dropdown menu and select "Scan and Repair".
  • 4. The client will then scan your game files and automatically repair any issues it finds.

Verifying your game files will ensure that any issues with the game's installation are resolved, helping you get back into the action faster.

Disable Overclock Settings


Overclocking is a popular technique used to boost performance in certain games. However, it can sometimes lead to stability issues, including Error 6345 in Warzone and Modern Warfare. To address this problem, you can temporarily disable overclock settings in your system. The process may vary depending on your system configuration, but here's a general guide:
  • 1. Restart your computer and enter the BIOS settings by pressing a specific key (e.g., F2 or Del) during startup. Consult your motherboard's manual for the exact key.
  • 2. Within the BIOS settings, locate the overclocking options and disable them.
  • 3. Save the changes and exit the BIOS settings.
  • 4. If you have overclocked your graphics card, you can use the manufacturer's software (e.g., NVIDIA Control Panel or AMD Radeon Software) to revert to the default settings.

While overclocking might boost performance in some cases, it can also introduce instabilities. Disabling it temporarily can help resolve Error 6345.

Additional Fixes:


Change COD Folder Settings


Modifying the COD (Call of Duty) folder settings can potentially fix Error 6345. Here's how you can access and modify these settings:

  • 1. Open File Explorer and navigate to the folder where Warzone or Modern Warfare is installed.
  • 2. Right-click on the game's folder and select "Properties".
  • 3. In the Properties window, navigate to the Security tab and click on "Edit" to modify the permissions.
  • 4. Ensure that your user account has full control over the folder by checking the box next to "Full Control".
  • 5. Click "Apply" and then "OK" to save the changes.

Update GPU Driver


Keeping your GPU (Graphics Processing Unit) driver up-to-date is crucial for an optimal gaming experience. Outdated drivers can cause various issues, including Error 6345. Here's how you can update your GPU driver:

  • 1. Open the Device Manager by pressing Win + X and selecting "Device Manager".
  • 2. Expand the "Display adapters" category.
  • 3. Right-click on your GPU and select "Update driver".
  • 4. Choose the recommended method to update the driver (e.g., search automatically online or manually download from the manufacturer's website).
  • 5. Follow the on-screen instructions to complete the driver update.

Delete Cache Files


Accumulated cache files can sometimes lead to errors and performance issues in Warzone and Modern Warfare. To resolve Error 6345, follow these steps to locate and delete cache files related to the games:

  • 1. Press Win + R to open the Run dialog box.
  • 2. Type "%localappdata%" (without quotes) and press Enter.
  • 3. Navigate to the "Battle.net" or "Blizzard Entertainment" folder.
  • 4. Locate the Warzone or Modern Warfare folder and delete it.
  • 5. Empty the Recycle Bin to permanently remove the cache files.


By following the outlined solutions, you'll be well on your way to enjoying a seamless experience in Warzone and Modern Warfare. Don't let Error 6345 hold you back from the action! Remember to close unnecessary background apps, verify game files, disable overclock settings, change COD folder settings, update your GPU driver, and delete cache files.
