Hunt: Showdown Easy Anti-Cheat Error: How to Fix It

Published

On this page

Hunt: Showdown’s Easy Anti-Cheat error almost always means the EAC service is corrupted, blocked, or flagging a system file — not that your account or hardware is broken. Easy Anti-Cheat runs as a separate background service from the game, and when its files, permissions, or trust checks fail, Hunt can’t launch even though the rest of your PC is fine.

Hunt: Showdown Easy Anti-Cheat Error: How to Fix It

This covers the most common Hunt: Showdown 1896 EAC failures — “Easy Anti-Cheat is not installed,” “EAC failed to start,” the “untrusted system file” error, and the anti-cheat hanging on launch — in the order most likely to fix them fast.

1. Run the EAC repair tool directly

This is the first thing to try and it clears most EAC errors without touching the rest of your install.

  1. Open your Hunt: Showdown install folder. On Steam that’s usually C:\Program Files (x86)\Steam\steamapps\common\Hunt Showdown\EasyAntiCheat.
  2. Right-click EasyAntiCheat_Setup.exe and select Run as administrator.
  3. Choose Hunt: Showdown in the game dropdown, then click Repair Service.
  4. Let it finish, then relaunch the game.

If the repair option fails or the EasyAntiCheat folder is missing, skip to the clean reinstall in step 6.

2. Fix the “untrusted system file” error

This error means EAC flagged a driver or Windows file it doesn’t trust — usually because something on the system is outdated or modified.

  1. Update your GPU driver (a clean install via DDU if it’s persistent) and your motherboard chipset drivers.
  2. Make sure Windows Update is fully current — EAC trusts signed, up-to-date system files.
  3. Open an elevated command prompt and repair Windows system files: 
    sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
  4. Reboot and relaunch Hunt.

3. Delete the corrupted EAC system file

A single corrupted EAC driver file can block launches while everything else looks fine.

  1. Fully close Hunt: Showdown.
  2. Open C:\Program Files (x86)\EasyAntiCheat_EOS.
  3. Delete EasyAntiCheat_EOS.sys.
  4. Restart your PC and relaunch — the file is recreated cleanly on the next start.

4. Check for antivirus or firewall blocking

Because EAC operates at a low level to detect cheats, security software sometimes flags, quarantines, or blocks it.

  1. Open your antivirus and check its quarantine or blocked items list for anything named EasyAntiCheat.
  2. Add both the Hunt: Showdown install folder and its EasyAntiCheat subfolder as exclusions.
  3. Temporarily disable third-party firewalls (not Windows Firewall) and test a launch — if it works, add a permanent exception instead of leaving protection off.

5. Confirm the Easy Anti-Cheat service is running

If the service is disabled and never starts, EAC can’t hook into the game.

  1. Press Win + R, type services.msc, press Enter.
  2. Find EasyAntiCheat (or EasyAntiCheat_EOS) in the list.
  3. Right-click → Properties → set Startup type to Manual or Automatic.
  4. Click Start if it isn’t running, then OK.

6. Uninstall and reinstall Easy Anti-Cheat cleanly

For errors that survive everything above, EAC needs a clean reinstall — separate from reinstalling the game.

  1. In the EasyAntiCheat folder, run EasyAntiCheat_Setup.exe as administrator.
  2. Select Hunt: Showdown and choose Uninstall.
  3. Reboot your PC.
  4. Relaunch Hunt — it redeploys EAC on the next start, or rerun the setup file and choose Install.

7. Rule out RGB, overlay, and monitoring software

EAC sometimes reads RAM RGB control, overlays, or memory-tuning tools as tampering and blocks the launch — a common Hunt-specific culprit.

  • Close third-party RGB and fan-control software during the first launch after a fix.
  • Close MSI Afterburner / RivaTuner (RTSS) and Discord’s in-game overlay while testing.
  • Once Hunt launches cleanly, re-enable them one at a time to find the culprit if the problem returns.

Most Hunt: Showdown EAC errors are a corrupted service, an untrusted driver, or a blocked install — not a ban or a hardware fault. Repair EAC and update your drivers first, then the file cleanup and clean reinstall clear whatever is left.

Frequently asked questions

Why does Hunt: Showdown say Easy Anti-Cheat is not installed?

EAC's files or its Windows service registration are missing or corrupted, usually after a 1896 patch, an antivirus deletion, or an interrupted install. Running EasyAntiCheat_Setup.exe from Hunt's install folder and choosing Repair fixes most of these cases without a full reinstall.

How do I fix the 'Easy Anti-Cheat untrusted system file' error in Hunt: Showdown?

That error means EAC flagged a driver or system file it doesn't trust — usually an outdated driver, a modified system file, or a disabled security feature. Update your GPU and chipset drivers, run sfc /scannow and DISM to repair Windows system files, and make sure Windows is fully updated, then relaunch.

Does deleting EasyAntiCheat_EOS.sys fix Hunt: Showdown launch errors?

Often, yes. Close the game, delete EasyAntiCheat_EOS.sys from C:\Program Files (x86)\EasyAntiCheat_EOS, then restart your PC and relaunch. The file is recreated cleanly on the next start, which clears many stubborn 'failed to start' errors.

Can RGB or monitoring software cause Hunt: Showdown EAC errors?

Yes. Easy Anti-Cheat sometimes detects RAM RGB control, overlay, or memory-tuning tools as tampering and blocks the launch. Close RGB/fan-control software, MSI Afterburner/RTSS, and overlays before launching, then re-enable them one at a time to find the culprit.

Where is the Easy Anti-Cheat folder for Hunt: Showdown?

It's inside Hunt's install directory in a subfolder named EasyAntiCheat — on Steam that's typically steamapps\common\Hunt Showdown\EasyAntiCheat. That folder holds EasyAntiCheat_Setup.exe, which repairs or reinstalls the anti-cheat service directly.
