Armored Core 6 Easy Anti Cheat Error 30005 [FIXED]

With the recent release of Armored Core 6, players have encountered the easy anti-cheat error 30005. This error makes Armored Core 6 crash as soon as you launch it. The error mainly only occurs on Windows 11 due to incompatibility issues with the easy anti-cheat and the new architecture offered by Windows 11. However, you might still notice the easy anti-cheat error 30005 on Windows 10.

Disable Kernel-Mode Hardware-Enforced Stack Protection

Kernel-mode Hardware-enforced Stack Protection is clashing with the EAC drivers for Armored Core 6, which leads to the EAC error 30005. For Windows 11, the only known solution is to disable Kernel Stack Protection. This also seems to work for several players sharing their experiences on this Steam forum post.

If you do not want to risk disabling Kernel Stack, another possible workaround is to revert your OS to Windows 10 to play Armored Core 6. Here’s how to do it:

1. Press the Windows icon + I on your keyboard simultaneously to open the Windows 11 settings.
2. From settings, navigate to Privacy & Security. Here, click on Windows Security.
3. Now click on Core Isolation Details. 
4. Here, toggle the switch to Off for Kernel-Mode Hardware-enforced Stack Protection.
5. To reactivate it once your session is complete, just switch it back to the “On” position.
6. Make sure to restart your PC after enabling/disabling Kernel Stack protection.

Disable Your Antivirus Software

Surprisingly enough, your antivirus software can be one of the bigger reasons why a game might be crashing or experiencing errors like EAC error 30005.

This happens when an antivirus software mistakes such an application for a potential virus. This phenomenon is uncommon and could be the reason behind the Armored Core 6 easy anti-cheat error 30005.

To check if this is the case, temporarily turn off your antivirus software and launch Armored Core 6 to see if the error gets fixed. If the error is fixed, proceed to whitelist the AC6 installation directory in antivirus settings. 

My antivirus has often prevented my games from launching. However, I always managed to fix the issue by whitelisting the game directory in the software. So go for it.

Verify Armored Core 6 Game Files

If the game files for Armored Core 6 are corrupted or missing, you can encounter the easy anti-cheat error 30005. Fortunately, Steam can easily identify and replace bad game files with new ones. This will help you fix the game’s issues without re-downloading the entire game.
