Fix 7: The Nuclear Option – Reinstall & Verify Integrity

If nothing else works, the install is corrupt at a binary level.

1. Verify Integrity: Steam > Library > Right-click BO2 > Properties > Installed Files > Verify integrity of game files. Wait for it to finish (it may find 1-2 missing files).
2. Clean Reinstall:
   • Uninstall the game via Steam.
   • Manually delete the folders: C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black Ops II AND %localappdata%\Activision\Call of Duty Black Ops II.
   • Reboot your PC.
   • Reinstall the game to your main C:\ drive (or an SSD without special permissions). Avoid external drives or drives with unusual file compression.

3. Add a command line argument in Steam

• Right-click Black Ops 2 in Steam → Properties
• Under Launch Options, paste: -dx9
• Close and relaunch

This forces the game to use DirectX 9, which is more stable for older COD titles.

Quick checklist (try these first)

• Restart your PC.
• Run Steam (or the game launcher) as Administrator.
• Verify game files via Steam (Library → right-click Black Ops II → Properties → Installed Files → Verify integrity of game files).
• Ensure Windows and GPU drivers are updated. If none of these work, follow the full steps below.
