Resolving the Ghost Recon Wildlands “Service Update Failed” Error
Nothing ruins a tactical deployment into Bolivia faster than the dreaded Ghost Recon Wildlands launch error service update failed. This error is primarily triggered by a desync or corruption within the Easy Anti-Cheat (EAC) system, or due to an outdated Ubisoft Connect PC client. When EAC fails to verify the game files or update its background service, it forcefully halts the launch process to prevent potential exploits.
Primary Causes of the Error
- Corrupted Easy Anti-Cheat Files: Recent Windows updates or game patches can corrupt EAC background services.
- Lacking Administrative Privileges: The game executable (GRW.exe) may not have the necessary permissions to initiate the anti-cheat update.
- Outdated Ubisoft Connect Client: Running an old version of the Ubisoft launcher can result in “A Ubisoft Server is unavailable” or service failures.
Step-by-Step Fixes for the Launch Error

The most reliable community-verified fix is to force EAC to repair itself directly from the game’s installation directory.
- Close the Ubisoft Connect launcher and Steam completely.
- Navigate to your Wildlands installation folder (e.g.,
C:\Program Files (x86)\Steam\steamapps\common\Wildlands\EasyAntiCheat). - Locate and run
EasyAntiCheat_Setup.exe. - Select Ghost Recon Wildlands from the dropdown menu and click Repair Service.
- If repairing fails, click Uninstall, then immediately Install it again.
Fix 2: Run GRW.exe as Administrator
Granting administrative rights ensures the game can modify and update files without Windows blocking the process.
- Find the main executable file:
GRW.exein your game folder. - Right-click it and select Properties, then navigate to the Compatibility tab.
- Tick the box that says “Run this program as an administrator”.
- Click Apply, then OK. Note: You may receive an EAC prompt asking if the game closed correctly after your sessions; simply click “Yes”.
