If you’ve ever launched a game protected by Easy Anti-Cheat (EAC) only to be met with the dreaded “untrusted system file” error, you’re not alone. The error message usually includes a long list of files that EAC doesn’t like, which can be incredibly frustrating. Many players search for help online and come across various troubleshooting steps, but unfortunately, most of these don’t resolve the issue.
With these steps, you should be able to fix the “untrusted system file” error with Easy Anti-Cheat and get back to gaming. Keep in mind that patience is key, as there isn’t a one-size-fits-all fix. But with the right troubleshooting, you’ll be able to resolve this frustrating issue.
The first piece of advice you’ll likely receive is to either verify the game files or reinstall the game. While this method can work in some rare cases, it’s not typically effective for this particular error. The key issue here is that the error specifies “untrusted system file,” not “untrusted game file.” This means the problem lies with your operating system, not the game itself.
Running system repairs like sfc /scannow or DISM /Online /Cleanup-Image /RestoreHealth can sometimes help, but these solutions are also only effective in rare cases. It’s often a waste of time, but since these commands don’t take long to run, you can try them if you wish.
Another common recommendation is to run the game or the anti-cheat as an administrator. However, this is generally a bad idea, especially in the gaming world. The only exception to this might be certain Chinese anti-cheats, such as the one used in Genshin Impact. In most cases, though, nothing requires administrative access.
So, what should you do instead? Here’s a simple guide to fixing the error yourself.
Understanding Easy Anti-Cheat
Easy Anti-Cheat works by scanning all active files to ensure they don’t contain any known vulnerabilities that could be exploited by cheaters. For example, if a system library like a DLL file has previously been vulnerable but has since been updated, EAC will flag the outdated version. EAC keeps track of files using certificates, stored in a special folder inside each game’s directory. If that certificate store becomes corrupted or outdated, you’ll run into errors.
The easiest way to resolve this is by forcing EAC to update its certificate store. To do this, delete both the certificates and licenses folders (if they exist) in the game’s directory, then run the EAC setup from the same folder and select the “repair” option. This will uninstall and reinstall Easy Anti-Cheat, which will refresh the certificate store.
Handling Specific System Files
In some cases, EAC will flag important system files, such as Microsoft Visual C++ redistributables. If you’re seeing issues with these files, the best solution is to reinstall all versions of Visual C++ redistributables. Many players mistakenly believe that simply installing the latest version will solve the problem, but you need to have all the versions (2005, 2008, 2010, 2012, 2013, 2015, 2017, and 2019) installed on your system.
The easiest way to do this is by downloading a cumulative pack that includes all the necessary redistributables. After unpacking the files, run the installation process to install all the required versions. This should resolve issues with system libraries that are causing EAC errors.
Windows Updates and Other Fixes
If the error is related to older Windows files, such as normal.dll or uxxx.dll, it’s a sign that your system may be outdated. EAC flags these files because they may contain security vulnerabilities that cheaters could exploit. If you haven’t updated your Windows in a while, it’s a good idea to install all available updates. This will ensure your system is secure and up-to-date.
Additionally, if you’ve been avoiding Windows updates out of fear of losing your Windows license, rest assured that updating your system will not impact your license. You will only lose your license if you’re using a pirated copy of Windows, but even then, updates will still download and install as long as you’re not using a very old, cracked version of Windows 7.
Steam and Other Software Issues
Easy Anti-Cheat may also flag issues with your Steam client, especially if you’re enrolled in the Steam Beta. In this case, you can simply exit the beta, restart your computer, and the problem should be resolved.
Sometimes EAC will flag other software, such as antivirus programs like Kaspersky. If this happens, make sure your antivirus program is fully updated. If it still causes issues, you may need to uninstall it altogether.
Reinstalling Windows as a Last Resort
In rare cases, EAC may complain about game files themselves, especially in cases like Raging P, an unofficial multiplayer for GTA V. The solution is straightforward: update the game and its associated software, like Rockstar’s Social Club.
However, if these steps don’t work, a complete reinstall of Windows might be necessary. Rather than resetting your system, I recommend performing a full reinstall. This means booting from a Windows installation media, deleting everything from your drives, and installing a fresh copy of Windows.
One potential solution to avoid reinstalling Windows in the future is to set up two separate installations: one for everyday use and one dedicated to gaming. This way, your gaming installation will have minimal software, reducing the chances of EAC and other anti-cheat systems flagging files.
