How to Fix Dev Error 6178 Modern Warfare?

Let’s explore the variety of solutions that can help you solve the error. Firstly, it is recommended that you run the game in compatibility mode to be sure if your game is compatible with the system or not.

Update Your Graphics Driver

The chances are that the error is occurring because your graphics driver is outdated. It’s best to update your graphics driver as soon as an update is available. This will help resolve the issue and improve the performance, allowing a smooth gaming experience.

To see whether a new version for the graphics drivers is available, go to the Device Manager and look for the graphic driver adapter. Then right-click to update the driver. It is recommended to restart your computer to make the update effective.

Disable In-Game Overlay

At times, the overlay features of any background application can cause your game to crash or get stuck. To prevent this from happening, switch off the overlay features of other applications as they might be conflicting with your game.

Moreover, not only this but you can also shut down any background apps to make sure they don’t interfere while your game is running. Overlay features are mostly preventing your current application from running smoothly; hence it’s better to close them.

Run Game as Administrator

If your Modern Warfare isn’t running as admin, the issue of error 6178 might surface. In this case, run your game as administrator to make sure it doesn’t lag or crash. Moreover, this will give your game full access to all the available game files on your device. To run the game as an administrator, do the steps below:

  1. Right-click on your Modern Warfare applications and go to Properties.
  2. Open the compatibility tab
  3. Select and check the Run as Administrator box.
  4. Press OK to confirm changes. Restart your device and check if the issue is resolved.

Shut Down Unnecessary Background Apps

Just like Overlay features, background applications running on your device will greatly interfere with your game’s performance. Not only this but since there will be a huge load on your device’s processor, your game might get crashed.

Hence before launching the game, you must ensure that all unnecessary tabs and apps that are not currently in use are closed.

Repair/Rename Corrupted Game Files

We all are aware of how corrupted files can become a headache. Well, it’s no surprise that they might be the culprit behind your error 6178.

Play in Windowed Mode

By playing in windowed mode instead of the display, the model is considered effective in preventing error 6178 from occurring. In the Graphics Settings of Modern Warfare, you can easily go to the display settings and choose the windowed mode for playing the game.
