The "DisplayName field missing from registry" error is common in EA Sports FC 26 on PC, and it usually happens because the game can't properly read its registry keys from Windows. This often occurs after installing through the EA App, Steam, or Game Pass.
Here's how you can fix it step-by-step
🔧 Fix "DisplayName field missing from registry" (EA FC 26)
1. Repair / Verify the Game Files
If you use EA App → Right-click the game → Manage → Repair.
If you use Steam → Right-click the game in Library → Properties → Installed Files → Verify integrity of game files.
This often restores the missing registry entries automatically.
2. Run as Administrator
Close the EA App.
Right-click EA App → Run as administrator.
Then launch FC 26 again.
(Sometimes the app doesn't have permission to update the registry without admin rights.)
3. Reinstall EA AntiCheat
Go to: C:\Program Files\EA\AC (or where you installed the game).
Run EAAntiCheatInstaller.exe.
Choose Uninstall, then Install again.
This fixes registry/launch issues tied to AntiCheat.
4. Check Registry Keys (Advanced)
⚠️ Only if you're comfortable with Registry Editor.
Press Win+R, type regedit, and hit Enter.
Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\EA Games\EA SPORTS FC 26
In the right panel, look for a string value called DisplayName.
If missing, create a new String Value → name it DisplayName → set its value to:
EA SPORTS FC 26
Restart your PC.
5. Clean Reinstall (Last Resort)
If nothing else works:
Uninstall the game.
Delete leftover folders in:
Documents\EA Sports FC 26
C:\Program Files\EA Games\EA SPORTS FC 26 (or your install path)
Reinstall the game via EA App or Steam.
This ensures registry entries are rebuilt fresh.
✅ Most users report Step 1 (Repair/Verify) or Step 4 (adding DisplayName manually) solves the issue.
