    Hey, please help!

    Whenever i try to install an update from windows update, i get an error. I
    have tried researching the problem to find a solution but i cant. There seems
    to be no solution. Can you please help? When i try to install the update,
    everything goes fine, it creates a restore point and then says installing 1
    of 1. I wait a minute or two and then it says

    Some updates weren't installed

    Error(s) found:
    Code 42B Windows Update encountered an unknown error

    The update i am trying to install is Microsoft SQL Server 2005 Express
    Edition Service Pack 3 (KB955706).

    Also tryed to DISABLE any anti-virus or Firewall programs then went into
    safe mode and download the update maunelly, and nothing...


    Thanks in advance.

  2. Carlo,

    Have you tried downloading the update from the Microsoft download center, and
    then installing it in Safe Mode?

  4. Carlo,

    Look in C:\Program Files\Microsoft SQL Server\90\Setup
    Bootstrap\LOG\Hotfix\SQL9Express_Hotfix_KB955706_SQLEXPR.EXE\Files; there should
    be a number of log files there. I'm hoping one of these will provide you with a
    more useful error message.

    You could also try the solution from this thread:


    Look at the last post, by Topspeak.
