    Tip: Temporarily disable real-time protection by your anti-virus and/or
    anti-spyware applications (e.g., CounterSpy, Spysweeper, Spybot, AVG
    Anti-Spyware) and/or any third-party firewall (e.g., ZA) before attempting
    to install the update(s).

    1. Can you install it manually? Save the download to your desktop then
    double-click on it to install:

    2. If no joy, see the Known Issues and "More information about..." sections

    The Windows Installer Service could not be accessed.
    This can occur if you are running Windows in safe mode,
    or if the Windows Installer is not correctly installed.
    Contact your support personnel for assistance.

    Try downloading the equivalent update and installing it manually?



    Good luck
