This means a Windows system file failed Easy Anti-Cheat's integrity check because it is corrupted or modified. Repairing the file resolves it. Jump to your situation below or work through the methods in order.
The EasyAntiCheat Untrusted System File error means a Windows system file (the message often names one, such as wldap32.dll or nvd3dumx.dll) failed EAC's integrity check because it is corrupted, modified, or from an unsupported Windows build. EAC blocks the game rather than trust a tampered file. The fix is to repair Windows' own files: run System File Checker (sfc /scannow) and, if needed, DISM to restore the health of the component store, then update Windows fully so the correct file versions are present. Reinstalling Easy Anti-Cheat refreshes its side. If you are on a Windows Insider build, EAC may not yet support it, and opting out and reverting to a stable release is the reliable fix. Once the flagged file passes its integrity check, the error clears.
Easy Anti-Cheat verifies core Windows files before letting the game run. The Untrusted System File error means one of those files, often named in the message, failed that check because it is corrupted, modified, or an unexpected version.
Repairing Windows resolves it: sfc /scannow and DISM restore the correct file, and a full Windows update brings versions in line. Reinstalling EAC refreshes its check, and opting out of the Insider program fixes cases where EAC does not support a preview build.
“Untrusted System File is EAC refusing to trust a Windows file that failed its integrity check, and it usually even names the file, something like wldap32.dll. The fix is to repair Windows, not EAC. I run sfc /scannow, follow with DISM if the store is unhealthy, and make sure Windows is fully updated so the right versions are in place. Then I reinstall EAC. The one gotcha is Windows Insider builds, EAC often does not support them, so you have to opt out and go back to a stable release.”
sfc /scannow DISM /Online /Cleanup-Image /RestoreHealth
The EasyAntiCheat Untrusted System File error means a Windows file failed EAC's integrity check. Run sfc /scannow and DISM to repair it, update Windows fully, and reinstall Easy Anti-Cheat. If you are on a Windows Insider build, opt out and revert to a stable release.
If sfc and DISM report a file they cannot repair, the named component often belongs to a driver or overlay that replaced the system DLL; updating or removing that software restores the genuine Windows file. You can also submit your error to us for a tailored fix.
