How To Fix the Delta Force ACE Center Exception Error

Delta Force is now available on PC and utilizes Tencent’s Anti-Cheat Expert (ACE) to combat cheaters and hackers. It’s effective for the most part, but can sometimes lead to stability issues in the game it’s deployed in. This is common for other anti-cheat technologies as well, especially those that operate at the Kernel level. If you’re running into the “ACE Center Exception Error” while trying to play Delta Force, here is how you can fix that.

Fixing the Delta Force ACE Center Exception Error

To fix the “ACE Center Exception Error” in Delta Force players need to reinstall ACE on PC. This is a pretty simple process and will reset the anti-cheat software to its original state. If that doesn’t work, we’ll change how the service behaves in Windows.

Reinstall ACE

• Make sure Delta Force isn’t currently running
• Open Steam and right-click on Delta Force
• Select Manage followed by Browse local files

• Now, navigate to the following folder:

Delta Force\Game\DeltaForce\Binaries\Win64\AntiCheatExpert

• In the AntiCheatExpert folder, open ACE-Setup64.exe
• This will uninstall and reinstall ACE

Launch Delta Force again and you should be able to progress without the error.

As an added measure, you can also verify the game files to make sure all the local files are in order.

• Open Steam and navigate to your library
• Here, right-click on Delta Force and select Properties
• In the Installed Files tab, click on Verify integrity of game files

Adjust the ACE Service in Windows

If reinstalling ACE doesn’t do the trick, we can adjust the anti-cheat service’s behavior in Windows so that it runs automatically.

• In Windows Search, type Services, and open the result
• Here, look for the following services:

AntiCheatExpert Protection AntiCheatExpert Services

• Right-click on the service, and select Properties
• Now, next to Startup Type, select “Automatic“

• Do this for both services and hit OK each time.

After you’re done, restart your PC and launch Delta Force. ACE should work properly now, and shouldn’t throw the exception error anymore.
