Highguard has launched, and players are eager to test it out, but some of them might have issues logging into the game. Since the game uses Easy Anti-Cheat, there might be a few issues that are preventing you from enjoying this sci-fantasy PvP shooter.
This guide summarizes the most common 'Fail to Launch' or Boot errors in Highguard, and offers solutions for every one of them. Stick around if you are having trouble playing, and check for your fix on the list below.
Highguard Global Release Times & Date
Here's a quick guide on Highguard's global release times and dates to help players find out when the game will be out for their particular time zone.
How to Fix Secure Boot Launch Error (Easy Anti-Cheat)
Most players are experiencing this troubleshooting issue, which is related to a BIOS option called Secure Boot. If players do not have this option enabled, they need to restart their PC, then run the BIOS (F2) and go to Security. Inside the Security tab, they will find the Secure Bios option disabled.
Make sure that in the 'Boot Configuration' tab of the BIOS, the CSM (Compatibility Module) option is 'Disabled' to turn on UEFI Mode. Hit save and wait for the system to reboot.
If their BIOS is not compatible with Secure Boot, then they will probably need to run through Windows Recovery. Follow the next Steps:
- Go to Settings, then Update & Security
- Go to Recovery and select Restart now under Advanced startup.
- On the next screen, select Troubleshoot
- Go to Advanced options, then UEFI Firmware Settings
- Restart to make changes.
This should have fixed the Secure Boot Launch Error, which is related to the latest versions of Easy Anti-Cheat. If the problem persists, then players might have one of the following issues:
File Integrity Checkup
It is also possible for the game to have some corrupted files that didn't download properly, or, if players participated in the Closed Tests, some files from previous installations might be causing conflicts with the current version of the game.
The best approach in this case is to check for File Integrity by going to Steam, then Library, and then right-click on Highguard and then Properties.
Inside Properties, players need to search for the 'Installed Files' tab and access it. Next, click on 'Verify Integrity of game files' to start the setup. Wait until it runs the diagnosis and then reboot Steam.
Make sure to close all Steam Services running on background. Access Task Manager, then look for all Steam Client Bootstraper (or similar instances) and close them up.
Easy Anti-Cheat Incompatibility (Older Version Installed)
If the problem persists or the game shows an 'Easy Anti-Cheat Incompatible Version' error, then the best approach is to uninstall all versions of Easy Anti-Cheat.
Go to Programs, Add or Remove Programs, and browse for the Easy Anti-Cheat uninstall option. Next, uninstall the game and re-download it to make sure the Anti-Cheat installation runs properly this time.
Reinstall The Game When A New Version Comes Out
If none of the options mentioned above worked, it will probably be best to Reinstall The Game after the developers deploy a Day1 Patch. These kinds of errors tend to happen due to software or hardware compatibility issues.
The best approach in this case, regretfully, is to wait for a later version of the game that has already included a fix inside the game files to prevent the launch error from happening.
