"EasyAntiCheat has encountered a launch error" or "EasyAntiCheat is not installed" appears when the anti-cheat can't initialize. This generic error has several common causes.
Affects any EAC-protected game: Fortnite, Apex Legends, Elden Ring, Rust, Dead by Daylight, Fall Guys, and more.
How to fix it:
- Always launch the game through Steam/Epic/the official launcher — launching the .exe directly bypasses EAC initialization
- Go to the game folder > EasyAntiCheat folder > run EasyAntiCheat_Setup.exe — select your game from the dropdown and click 'Install' or 'Repair'
- Make sure the EasyAntiCheat service isn't disabled: open Services (services.msc), find EasyAntiCheat, set it to Manual
- Run the game as Administrator
- Disable other anti-cheat software temporarily — having BattlEye and EAC both running can sometimes conflict
- Verify game files through your launcher
- Temporarily disable your antivirus to test if it's blocking EAC
- Reinstall the game if nothing else works — make sure to delete leftover EAC folders before reinstalling
