  2. Not surprisingly - I have no idea what you mean by, "i've tryed all sort of
    way and nothink works"; I translated that to, "I've tred all sort of
    way [to install these updates] and nothing [has] work[ed]". First - not
    defining your "sort of way" leaves one at a loss at what you have
    tried. Second, "not thinking" seldom solves the problem. *vbeg*

    Download each and install them manually.
    (Select the one for your OS)
    (Select the one for your OS)

    Yes - that covers all 4.

    Otherwise (or actually - do these steps in *any case*)...

    Download, install, run, update and perform a full scan (separately) with the
    following two applications (freeware versions are the ones to use for this):



    After performing a full scan with one and then the other and removing
    whatever they both find completely, you may uninstall these products,
    if you wish.

    Download and run the MSRT manually:


    Assuming you have 32-bit Vista - Follow these steps...

    How do I reset Windows Update components?


    Try to update again.

    Last resort...

    [Worked for me] Do this :
    _Code_646_ - If the Updates you are trying to install are Securit
    Updates for Microsoft Office, Check if u Have Microsoft Silverlight i
    the Optional section. Now make sure to check All the needed updates an
    Silverlight [Even though its Optional]. Now install, everything wil
    come out Great :] GL

    I opened a call with microsoft and they suggested also renaming th
    SoftwareDistribuition folder this did not help.

    What fixed the probelm for me was to install an Optional Update Calle
    Office Live Update 1.4 after doing this the remaining two updates di

    I've complained to Microsoft about an Optional Update be Required t
    get Non Optional updates to install but as yet the person I'm workin
    with does not seem to understand the problem.

    Hope this works for others also
