8 Fixes: Solve Easy Anti-Cheat Untrusted System File Error - 100% Working

Part 1. What is the Easy Anti-Cheat Untrusted System File Error, & Why It Occurs?

Easy Anti-Cheat untrusted system file error is the error that appears when the EAC service suspects that a computer file is insecure, manipulated, or damaged. As EAC is meant to provide fair play in online games, it will block the launch of the game in case of any suspicious file.

This often shows error messages such as:

• "Easy Anti Cheat Untrusted System File globalroot device"
• "Easy Anti-Cheat Untrusted System File steamclient64.dll"
• "Untrusted system file system32"

Essentially, EAC prevents you from entering the game until it verifies that your system files are safe and authentic.

The most common reasons behind this error include:

• Modified or Replaced DLL Files: Third-party software or modding tools may alter core DLL files like steamclient64.dll or vcruntime140.dll.
• Faulty Graphics or System Drivers: Old drivers may conflict with EAC's real-time scanning system.
• Antivirus or Security Software Interference: Some antivirus programs quarantine EAC-related files by mistake.
• Corrupted EAC Installation: The Easy Anti-Cheat component itself might be outdated or corrupted.

Part 2. How to Fix Easy Anti-Cheat Untrusted System File Issue [7 Solutions]

If you are facing this issue, you can follow the methods below to fix it with ease:

1. Run EasyAntiCheat_Setup.exe as Administrator and Repair the Game

In case of the Easy Anti Cheat untrusted system file error that is caused by the absence or loss of the EAC components, the service can be repaired immediately. The setup tool can be executed as an administrator to repair damaged files, such as steamclient64.dll or EACLauncher.exe, that can be mangled during updates or affected by antivirus software.

• Open your game's installation folder and go to: Game Folder > EasyAntiCheat > EasyAntiCheat_Setup.exe. (Or, via Steam: Right-click game > "Properties" > "Local Files" > "Browse" > then locate the EAC setup).

• Right-click it and select "Run as Administrator", then click "Repair Service" and wait until it finishes.

  

• Restart your PC and relaunch the game.

2. Run Windows Update to Fix System Files

System files that are also necessary to Easy Anti-Cheat might be outdated or incompatible with a large Windows patch. The Windows update will help to sign and trust all core drivers and libraries.

This works especially well in solving errors like globalroot devices or incompatible kernel modules that result in EAC refusing to accept system files.

• Open Windows "Settings" and go to "Windows Update", then click "Check for Updates".

• If any updates are available, you must download and install them to fix the easy anti cheat untrusted system file issue.

  

3. Run System File Checker (sfc /scannow)

In some cases, the untrusted system file message is brought about by corrupted or unsigned Windows system files in the System32 directory. By executing the System File Checker command, Windows will automatically scan, detect, and replace faulty files.

When the game starts, the Easy Anti-Cheat engine identifies the problematic files as harmless and legal.

• Open Command Prompt as Admin on your computer and run the command: sfc /scannow.

• Optionally, run DISM /Online /Cleanup-Image /RestoreHealth first if SFC fails, then rerun SFC.

• Let the command execute, and when it is done, you can restart your computer.

  

4. Reinstall Microsoft Visual C++ Redistributable

Most games are based on Microsoft Visual C++, which is checked by Easy Anti-Cheat when launching the game. In case the libraries like vcruntime140.dll or ControlLib.dll are missing or corrupted, the game is blocked by EAC.

These necessary runtime dependencies can be reinstated by installing the full Visual C++ package again, and this removes compatibility problems with supported titles.

• Open "Control Panel" and click "Programs", then choose "Programs and Features".

• Uninstall all "Microsoft Visual C++ Redistributable" versions.

  

• Visit Microsoft's official site and download the latest 2015–2022 x86 and x64 packages. Install them both and restart your computer.

  

5. Update/Reinstall Specific Graphics Drivers (e.g., Intel Graphics)

The untrusted file warning of Easy Anti-Cheat may be caused by old or blank graphics drivers, Intel or NVIDIA display drivers, in particular.

This is because updating to the most current WHQL-certified version will replace all the modified or insecure driver binaries, and your graphics stack will be verified by EAC, and your game will be able to boot as usual with no security issues.

• Press "Windows + X" and choose "Device Manager".

• Expand "Display adapters" and right-click your graphics card, select "Update driver" and choose "Search automatically for drivers".

  

6. Verify Game Files Integrity

In some cases, Windows is not the cause of the untrusted system file error, but rather it is the corrupted assets of the game. Checking game file integrity by checking files with Steam, Epic Games, or EA Apps, and checking files against their official versions.

Missing or mismatched Easy Anti-Cheat data is then automatically fixed or re-downloaded by the launcher.

• Open Steam and go to "Library" and right-click your game and select "Properties".

• Click "Local Files", then click "Verify Integrity of Game Files" and wait until the verification process completes.

  

7. Update or Reinstall Easy Anti-Cheat

Otherwise, your Easy Anti-Cheat installation can be destroyed as well. A reinstallation guarantees the most recent trusted build that is provided by the developer. This will cleanse any leftover corrupted files and restart the EAC service, fully cleaning up the lingering untrusted system file errors in games such as Apex Legends or Fortnite.

• Open the "EasyAntiCheat" folder inside your game's directory and run "EasyAntiCheat_Setup.exe".

• Select your game from the list and click "Uninstall".

• Once done, click "Install Easy Anti-Cheat again" and restart your PC before relaunching the game.
