Dead by Daylight Easy Anti-Cheat (EAC) Error: How to Fix It

Published

On this page

Dead by Daylight’s Easy Anti-Cheat error almost always means the EAC service itself is corrupted, blocked, or missing — not that anything is wrong with your account or your PC’s hardware. EAC runs as a separate background service from the game, and when its files, permissions, or registration break, Dead by Daylight can’t launch even though the rest of your system is fine.

Dead by Daylight Easy Anti-Cheat (EAC) Error: How to Fix It

This covers the most common Dead by Daylight EAC failures — “Easy Anti-Cheat is not installed,” “EAC launch error,” and the anti-cheat hanging on startup — in the order most likely to fix them fast. These errors spike after big chapter updates, so start with the repair tool and file verification.

1. Run the EAC repair tool directly

This is the first step Behaviour recommends, and it clears most EAC errors without touching the rest of your install.

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

If the repair option fails or the EasyAntiCheat folder is missing entirely, skip to the reinstall step below.

2. Verify the game files first after any update

Because Dead by Daylight’s EAC errors most often appear right after a patch, resyncing the files clears a big share of them.

  1. In Steam, right-click Dead by Daylight in your library → Properties.
  2. Go to Installed Files → Verify integrity of game files.
  3. Let it finish, then rerun the EAC repair from step 1 and launch again.

3. Run Dead by Daylight and EAC as administrator

EAC needs elevated permissions to install and register its service. Without them it fails silently or throws a generic error.

  1. Right-click EasyAntiCheat_Setup.exe (same folder as above) → Properties → Compatibility tab.
  2. Check Run this program as an administrator → Apply → OK.
  3. Do the same for your Steam shortcut.
  4. Relaunch Dead by Daylight.

4. Check for antivirus or firewall blocking

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

  1. Open your antivirus app and check its quarantine or blocked items list for anything named EasyAntiCheat.
  2. Add both the Dead by Daylight install folder and the 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 or set to Manual and never starts, EAC can’t hook into the game.

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

6. Uninstall and reinstall Easy Anti-Cheat cleanly

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

  1. In the EasyAntiCheat folder, run EasyAntiCheat_Setup.exe as administrator.
  2. Select Dead by Daylight and choose Uninstall.
  3. Reboot your PC.
  4. Launch Dead by Daylight — it redeploys EAC automatically on the next start, or you can rerun the setup file and choose Install.

7. Rule out overlays and conflicting software

FPS overlays and RGB/monitoring tools occasionally interfere with EAC’s process checks.

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

Most Dead by Daylight EAC errors are a corrupted service, a blocked install, or a post-update file mismatch — not a ban or a hardware fault. Verify your files, run the repair tool, and the clean reinstall in step 6 clears whatever is left.

Frequently asked questions

Why does Dead by Daylight say Easy Anti-Cheat is not installed?

EAC's own files or its Windows service registration are missing or corrupted, usually after a game update, an antivirus deletion, or an interrupted install. Repairing EAC directly from the Dead by Daylight install folder fixes the large majority of these cases without a full reinstall.

Where is the Easy Anti-Cheat folder for Dead by Daylight?

It's inside the Dead by Daylight install directory in a subfolder named EasyAntiCheat (on Steam, typically steamapps\common\Dead by Daylight\EasyAntiCheat). That folder holds EasyAntiCheat_Setup.exe, which you run to repair or reinstall the service directly.

Why does Dead by Daylight give an EAC launch error only after an update?

Behaviour ships EAC updates alongside game patches, and an interrupted or partially applied update can leave the anti-cheat service out of sync with the new build. Verifying the game files in Steam and then running the EAC repair tool resyncs them, which clears most post-update launch errors.

Does antivirus software cause Dead by Daylight EAC errors?

Yes. Antivirus and firewall tools sometimes quarantine or block EAC's kernel-level service because of how it hooks into the system to detect cheats. Add both the Dead by Daylight install folder and its EasyAntiCheat subfolder as exclusions before trying anything else.

Will reinstalling Dead by Daylight fix a persistent EAC error?

Usually not by itself — EAC lives in its own folder separate from most of the game's files. Uninstall Easy Anti-Cheat specifically first via its own setup.exe, reboot, then verify or reinstall Dead by Daylight so EAC gets deployed fresh.
