Error when Starting Steam

Exit Steam and delete everything under the Steam installation directory except Steam.exe and the \SteamApps folder - then start Steam using the Steam.exe application in this folder (not a previous shortcut) - this will force Steam to update when you log in.



Edit only the Windows registry key specified - editing some Windows registry keys may damage your computer's operating system or cause unpredictable behavior.

  1. Ensure that Steam is not running (close any error dialog windows).
  2. Go to the Start button and select Run....
  3. Enter regedit and press OK.
  4. Navigate to the HKEY_CURRENT_USER\Software\Valve\Steam registry folder.
  5. Locate and double-click the Language registry key.
  6. Enter english in the Value data field and click OK.
  7. Start Steam.
