Some players may see the “Easy Anti-Cheat Not Installed” error when trying to launch a game on Windows. This usually happens if the EAC service isn’t installed properly, the configuration file is missing, or your antivirus accidentally removed a file. Don’t worry, this guide will show you a quick and easy way to reinstall EAC and get back to gaming.

What is Easy Anti-Cheat?

Easy Anti-Cheat (EAC) is a security tool designed to prevent cheating in online multiplayer games. Many popular games like Fortnite, Apex Legends, and Dead by Daylight rely on EAC to ensure fair play. When EAC fails to install or load, the game cannot start, and you may encounter the Easy Anti-Cheat not installed message. This can happen due to:

• Missing or corrupted EAC files

• Conflicts with antivirus software

• Issues with Windows services or permissions

• Game installation errors

Reinstall Easy Anti-Cheat Manually

In many cases, the error occurs because the EAC service was not installed correctly. Reinstalling it manually often solves the problem.

Step 1. Locate the game’s root directory. Then open the following folder: Game Folder -> EasyAntiCheat. Inside the folder, find the file: Settings.json.

Step 2. Open Settings.json using Notepad. Look for the line containing: productid. Copy the productid value. Each game or installation has a different ID.

Step 3. Open Notepad and enter the following command: easyanticheat_eos_setup.exe install +productid. Replace “productid” with the value you copied earlier.

Step 4. Save the file with the .bat extension. If you cannot see file extensions, enable “File name extensions” in Windows Explorer.

Step 5. Once finished, double-click the .bat file you created. This command will reinstall Easy Anti-Cheat, which usually resolves the error.
