Highguard has officially launched, sparking excitement among players. However, some may encounter login difficulties due to the game’s integration with Easy Anti-Cheat. This troubleshooting guide highlights the most prevalent ‘Fail to Launch’ or boot errors, offering effective solutions to enhance your gaming experience. If you’re facing challenges launching the game, keep reading to find your solution in the list provided below.
Resolving Secure Boot Launch Errors (Easy Anti-Cheat)

A significant number of players have reported issues related to a BIOS setting known as Secure Boot. To resolve this, users should restart their PC, access the BIOS (by pressing F2), and navigate to the Security tab. There, they will likely find the Secure Boot option disabled.
Additionally, within the ‘Boot Configuration’ tab of the BIOS, ensure that the CSM (Compatibility Support Module) option is set to ‘Disabled’. This setting allows UEFI Mode to be activated. Remember to save the changes before allowing the system to reboot.
If your BIOS does not support Secure Boot, you may need to follow a recovery process through Windows. Here are the necessary steps:
- Access Settings, then navigate to Update & Security.
- Select Recovery and click on Restart now under Advanced startup.
- From the subsequent screen, choose Troubleshoot.
- Navigate to Advanced options, then select UEFI Firmware Settings.
- Restart to apply changes.
Following these procedures should alleviate the Secure Boot Launch Error associated with newer versions of Easy Anti-Cheat. If issues persist, consider the following potential problems:
Checking File Integrity

Another common issue is the presence of corrupted game files, which may not have downloaded correctly. Players who participated in Closed Tests might find residual files from previous installations conflicting with the current game version.
To check for file integrity, open Steam, navigate to your Library, right-click on Highguard, and select Properties.
Within the Properties menu, locate the ‘Installed Files’ tab and choose ‘Verify Integrity of game files.’ Once the verification process is complete, restart Steam. Remember to close any running Steam services in the background via the Task Manager by identifying and terminating all instances of Steam Client Bootstrapper or similar processes.
Easy Anti-Cheat Incompatibility (Outdated Version)

If players continue to experience issues or receive an ‘Easy Anti-Cheat Incompatible Version’ error, it’s advisable to uninstall all versions of Easy Anti-Cheat.
To do this, head over to Programs, select Add or Remove Programs, then locate the Easy Anti-Cheat uninstall option. Next, uninstall Highguard. Afterward, re-download the game to ensure a proper installation of the Anti-Cheat component.
Reinstalling the Game After Updates
If none of the aforementioned solutions resolve the problem, consider reinstalling Highguard once developers release a Day-1 Patch. Launch errors typically arise due to software or hardware compatibility issues.
In such cases, the best course of action is to wait for a post-launch update that addresses these errors in the game files, ultimately improving your experience.
