    The following solution worked for me on a PC running Vista SP1. This was after all of the other suggestions provided by Microsoft Support at http://support.microsoft.com/kb/836941 and http://support.microsoft.com/kb/971058 did not work.

    Solution (Vista SP 1):

    1. Click the “Start” Button, click “All programs”, and click “Accessories”.
    2. Right-click “Command Prompt” Run as administrator”. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
    3. Type “netsh winhttp reset proxy” (without quotes) at the command prompt, and press Enter.
    4. Try the update again.
