That 0xc0000005 error can crash Warzone when it pops up, which spoils the game’s fun. Does the same thing happen when you play that game? This is how you can fix Warzone’s 0xc0000005 error in Windows 11 and 10.

1. Run a Repair Scan for Warzone

One resolution the 0xc0000005 error message suggests is to run a repair scan for Warzone (ModernWarfare.exe). That error message even includes a Scan and Repair button, but some players have said clicking it crashes the game. Therefore, we recommend you select Scan and Repair for Warzone in Battle.net as follows:

First, open Warzone’s Battle. net launcher software. Click Battle. net’s All Games button, and select the My Games option. Select your Warzone game. Click Options (the cog icon) on the right side of Warzone’s Play button. Then select the Scan and Repair option. Click Begin Scan to confirm.

Now, wait for the repair scan to finish. It may take a while because Call of Duty: Warzone is a big game.

2. Select GeForce Experience’s Optimize Option for Warzone

If your PC has an NVIDIA graphics card, this is one resolution worth trying. Some Warzone players have said they were able to fix the 0xc0000005 error by selecting Optimize for Warzone in GeForce Experience. You can download that software from the NVIDIA GeForce Experience page if needed. This is how you can select Warzone’s Optimize option in that software:

Right-click the NVIDIA icon in the system tray and select GeForce Experience from there. Move your cursor over Modern Warfare on the Home tab. Select the Details option. Click the Optimize button.

If you don’t see Modern Warfare (Warzone) on the Home tab, click the Settings button. Select the Games & Apps > Scan Now option. Then you’ll see the game in GeForce Experience.

3. Set Warzone to Run With DirectX 11

DirectX 12 is a more advanced DirectX version than DX11, but it can cause Warzone crash errors. You can configure Warzone to run with DirectX 11 by inputting a command line argument for it as follows:

Bring up Warzone in the Battle. net software. Click Options on the Play button to select Game Settings. Then click the Call of Duty: Warzone game in the Game Settings tab. Select Additional command line arguments to activate a text box. Input -d3d11 in the text box for command line arguments. Press the Done button.

4. Update the Graphics Driver for Your GPU

Call of Duty: Warzone has fancy graphics, making it more important to install the latest NVIDIA or AMD graphics drivers. Warzone issues like error 0xc0000005 will more likely occur when your GPU’s driver is many months or even years old. You can update GPU drivers with one of the methods in our guide to updating graphics drivers on Windows.

5. Rename Warzone’s Modern Warfare Folder

Have you tweaked Warzone’s in-game graphics and audio settings in any way? If so, resetting all its options to default could be a viable solution for the 0xc0000005 error. You can restore the game’s default settings configuration by renaming its Modern Warfare folder in the following steps:

First, launch File Explorer, which has a handy Windows key + E hotkey for opening it. Select Documents in the File Explorer’s navigation sidebar. Right-click the Call of Duty Modern Warfare option and select Rename. Input Call of Duty Modern Warfare backup to be the new folder’s title. Warzone will then recreate a new folder when you launch the game again.

6. Turn Off NVIDIA Highlights

Do you play Call of Duty: Warzone with NVIDIA GeForce Experience’s overlay? If you do, try disabling that overlay’s Highlights feature for automatically capturing snapshots and recordings from games with ShadowPlay. This is how you can turn off NVIDIA Highlights:

Bring up NVIDIA GeForce Experience by right-clicking its system tray icon and selecting it from there. Then click the Settings cog button. Press the Settings button for the in-game overlay. Select the Highlights option. Disable the Capture setting.

Alternatively, you can disable Highlights specifically for Warzone. To do so, open the Highlights settings from the GeForce Experience overlay when playing the game and turn off the Call of Duty: Modern Warfare option.

7. Disable the On-Demand Texture Streaming Graphics Setting

On-demand Texture Streaming is a graphical setting in Warzone that boost the game’s colors by streaming textures. However, that setting is a potential cause of error 0xc0000005 for players with lower internet bandwidths. Nor does that option make an especially noticeable enhancement to the game’s visual quality. These are the steps for disabling On-demand Texture Streaming in Warzone:

Launch the Call of Duty: Warzone game. Click Options at the bottom of Warzone. Select the Graphics tab. Next, click Disabled for On-demand Texture Streaming. Select the Yes option when prompted to confirm you’re sure about disabling that setting. Then restart Warzone to apply the setting.

Stripping down other graphical settings in Warzone will also free up system resources while playing the game. Warzone will be less likely to crash on lower-specification PCs when playing it with lower graphics options. So, consider lowering, or even disabling, other display and quality settings for that game.

8. Disable the ASUS GameFirst VI Background Software

ASUS GameFirst VI is an integrated network program known to conflict with Call of Duty: Warzone. Some players have fixed error 0xc0000005 by disabling that software. If you don’t need or want GameFirst VI, we would recommend uninstalling it via Settings. However, you can disable that app like this:

Bring up the Task Manager tool (pressing Ctrl + Shift + Esc opens it). Select Task Manager’s Startup tab. Then select GameFirst VI in the Startup tab, and click its Disable button. Right-click the GameFirst VI process on the Processes tab and select End task. Play Warzone again with GameFirst disabled or uninstalled.

GameFirst VI probably isn’t the only background app that conflicts with Warzone. We also recommend players clean-boot Windows 11/10 to turn off superfluous startup apps and services. Check out our guide about performing a clean boot in Windows to know more.

9. Reinstall the Battle.net Client

Some players have said reinstalling Battle.net fixed Warzone’s 0xc0000005 error on their PCs. Note that reinstalling that software doesn’t delete Battle.net games, so it shouldn’t take long to get back to gaming. You can uninstall Battle.net via Programs and Features, as outlined in our uninstalling Windows 11/10 software guide.

To reinstall Warzone’s gaming client, open the Battle.net downloads page; click Battle.net Desktop App for Windows there. Then open the Battle.net setup wizard from your browser or File Explorer to reinstall the software.

10. Reinstall Call of Duty: Warzone

Warzone is a big game to download and install again, but if nothing else works, try reinstalling it as a last resort for fixing the 0xc0000005 error. Reinstalling Call of Duty: Warzone is the most surefire way to resolve issues with the game’s installation. Follow these steps to reinstall Warzone via Battle.net:

Open the Call of Duty: Warzone page in the Battle. net app. Click Options to view that menu. Select the Uninstall option from there. Click Yes, Uninstall to confirm. Reinstall Warzone by pressing the Install button in Battle. net for that game.

If you’re using a laptop, make sure it’s plugged in while waiting for Warzone to reinstall. Then you might as well go and watch the TV or read a book, for it will probably take at least a few hours to download.

Enjoy Call of Duty: Warzone’s Blasting Action Again

Applying those potential fixes will probably stop the 0xc0000005 error spoiling Warzone’s blasting action for most players who need to resolve that issue. There’s no guaranteed way to fix that error, but those solutions have worked for some players.

You can also try generic fixes like cleaning up a full hard drive to open up space, running an SFC scan to check for corrupted files, and disabling G-Sync to fix the 0xc0000005 error.
