Navigate to the loc folder inside the game directory. Delete the existing eng folder. Now, drag the new eng (Extra Quality) folder from your download into the loc folder.

The "Extra Quality" pack contains a .pak file called Crusader_English_voice_high.pak . Drag this into the bin folder. When Windows asks if you want to replace the existing file, click Yes .

Navigate to your Stronghold Crusader directory (e.g., C:\Program Files (x86)\Steam\steamapps\common\Stronghold Crusader ). Copy the bin folder and loc folder to your desktop. Rename this backup to loc_original . Why? If the pack corrupts your game, you need these files.
