If the language selection is not available in the game's "Properties" menu on Steam, you can follow this community-proven manual method: Locate Game Folder : Navigate to the installation directory, typically:
Clear your Steam download cache (Steam > Settings > Downloads > Clear Download Cache). Then verify integrity of game files (Properties > Local Files > Verify integrity). Steam will re-request the English pack.
Locate the game's root directory (usually C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Advanced Warfare\ ). Inside the global edition, navigate to the folder. Copy the english folder.
Always stick to official platforms like Steam, the Xbox Network, or the PlayStation Store to update your game files safely and legally. Summary Checklist for Troubleshooting
