Easy AntiCheat Error: Fix EAC Launch Failures
Independent guide — no official affiliation with the platforms mentioned.
Short answer
Easy AntiCheat (EAC) errors stem from the game's EAC module being missing, the service failing to start, or corrupted files. The fix: run the game's EasyAntiCheat_setup.exe tool, start the EAC service manually, verify files and set antivirus exclusions. Most 'Launch Error' dialogs close with the setup tool.

01 — Step-by-step fix
Step-by-step fix
STEP 01
Run the EAC setup tool
In the game's install folder find EasyAntiCheat_setup.exe (or EasyAntiCheat_EOS_setup.exe) and run as administrator. Select the game and click Install/Repair. In Fortnite it lives under FortniteGame; for Elden Ring, in the game root.
STEP 02
Start the EAC service manually
Open services.msc, find EasyAntiCheat (or EasyAntiCheat_EOS) and press Start. If the service is missing, the setup tool from step 1 creates it.
STEP 03
Verify game files
Steam: Properties > Installed Files > Verify; Epic: the game's three-dot menu > Manage > Verify. A corrupted EasyAntiCheat.sys gets replaced.
STEP 04
Configure antivirus and firewall
Exclude the EasyAntiCheat folder (usually C:\Program Files (x86)\EasyAntiCheat_EOS) in your antivirus. Allow EAC network access in Windows Defender Firewall; if you denied the permission prompt at first install, re-enable it in firewall settings.
STEP 05
Last resorts
If the error persists: install the latest Windows updates, disable test-signed drivers (bcdedit /set testsigning off) and restart. Still failing? Uninstall the game, delete the EAC folder manually and do a clean install.
Tips
- If the game throws EAC errors every launch, also run Steam/Epic as administrator.
- On Windows Home, disabling Hyper-V (Turn Windows features on/off) improves EAC stability.
- If the EAC setup tool fails with 'cannot install service', temporarily disable real-time antivirus protection and retry.
02 — Frequently asked questions
Frequently asked questions
Why does 'Easy AntiCheat is not installed' appear?
An incomplete EAC folder or antivirus blocking the EAC setup produces this error. Running the setup tool as administrator and choosing Install solves it.
What do EAC codes (10011, 3005, etc.) mean?
10011 usually means a driver conflict, 3005 a corrupted installation. Official meanings are listed on Easy AntiCheat's support page; search the code for code-specific steps.
I don't cheat, yet I get kicked/banned. Why?
Some RAM/XMP profiles, virtual machine software (VirtualBox, Hyper-V) or old kernel drivers (especially RGB/camera tools) trip EAC's memory verification. Setting XMP to default and removing VM software usually fixes it.
