Problem overview

Games protected by Easy Anti-Cheat (EAC) fail to start, throwing Error 30005 along with a “CreateFile failed” message. This prevents you from launching the game completely.

Common causes

  • Corrupted EAC installation files
  • Antivirus or Windows Defender blocking or quarantining EAC components
  • Missing administrator permissions for the game or launcher
  • Leftover driver files from previous EAC sessions locking the system

Solution 1: Repair the Easy Anti-Cheat service

  1. Navigate to the installation folder of the game causing the error.
  2. Open the EasyAntiCheat folder (sometimes found inside an _installer folder).
  3. Right-click on EasyAntiCheat_Setup.exe and choose Run as administrator.
  4. Select your game from the dropdown menu and click Repair Service.
  5. Wait for the process to finish and click Finish.
Expert Tip

If the repair option is grayed out, choose to install it instead.

Solution 2: Delete the sys file and verify integrity

  1. Navigate to C:\Program Files (x86)\EasyAntiCheat.
  2. Locate the file named EasyAntiCheat.sys and delete it.
  3. Open your game launcher (Steam, Epic Games, etc.).
  4. Right-click the game in your library and navigate to its properties.
  5. Select Verify integrity of game files to redownload a fresh copy of the missing file.

Solution 3: Check your antivirus software

  1. Open your antivirus or Windows Security dashboard.
  2. Navigate to your protection history or quarantine section.
  3. Look for any files related to EAC or your game executable.
  4. If found, restore the files and add the game’s installation folder to your antivirus exceptions list.
Caution

Never disable your antivirus completely while playing online games. Only add specific folder exceptions for trusted software.

Confirm the result

  1. Repeat the exact action that originally triggered the problem.
  2. Confirm the original error or symptom is gone and no new warning has appeared.
  3. If the guide changed a driver, service, package, or system setting, restart once and test again.
  4. If the result is worse or unexpected, stop. Reverse only the last change using its documented restore option; if none is documented, use your backup or qualified support.

Questions about this fix

Why does Error 30005 happen?

It usually means a file Easy Anti-Cheat needs is locked, missing, or blocked by antivirus software.

Does reinstalling the game fix it?

Sometimes, but repairing the EAC service directly is much faster and usually solves the issue.
