    Each I time get error 00000646 that updates failed. Tried manual update as
    mentioned in other notes and get error that update is already installed. Yet,
    still appears as a critical update on windows updates. Appreciate any help -

  2. See if temporarily disabling UAC allows the updates to install.

    try disabling User Account Control first before downloading the update
    manually. See: (Guided Help: Adjust User Account Control settings in Windows

    install the updates, reenable UAC.

    or just disconnect from the internet and try to install the updates. You
    might have to reboot first.
