    Hello Members, i hope someone has the answer.

    I'm having a major issue trying to get this update to install, somethings
    very wrong, i've already read another thread regarding this update, but as
    yet no one has the answer.

    The computer again is a Dell Inspiron 1720, Intel graphics chipset, 160gig
    HD, with 2gig of ram, the Windows Vista SP1 was offered for install a month
    ago, and i accepted it.

    The system does not have windows defender on it, or running as far as i can
    tell in the systray, and i only use Windows live Mail as my email client, the
    firewall is handled by McAfee Security center(same as the other members

    I have tried to install the update from a downloaded version, with the same
    error, so now i'm hoping a forum member might have the solution, or who to
    contact about the issue.

    Your help would be very grateful.

    Kind regards

  3. The system does not have windows defender on it

    Windows Defender is included in Vista by default.
    Were all components of McAfee Security Center running in the background when
    Vista SP1 was installed?

    Have you been able to successfully install any other Windows Updates since
    Vista SP1 was installed a month ago?

    Hello and thanks to all the replies, i haven't had the chance to try either
    doing the update with McAfee off, or following the other links, as i'm away
    from my computer for a few days, so i hope i may bring this post alive again
    when i give it a go.

    What i can say is when i first noticed this problem originally there were 2
    window vista updates needed, they were both downloaded, and the install
    process began, one was successfully installed, but the one above was not, and
    hasn't been ever since.

    I haven't been offered further updates, so i can't tell if any others would
    download, and install at the moment regardless of this one.

    As far as the Service Pack 1 installation was concerned, "yes" i did leave
    McAfee, and anything else running in the systray at the time, i didn't think
    to turn them off at the time, but also saying this, there were no prompts
    from the apps during the SP1 install.

    What i can say is, i didn't have any other apps running, either during the
    SP1 install, or when i did the vista updates, like IE7 or Windows Live Mail.

    What does worry me though is the comment regarding having to install the OS
    again, i hope there may be a way to repair it, like the SFC type tool or

    Theres just one last comment i would like to mention, and that is the
    computer runs like a dream, there doesn't appear to be any other issues, no
    other problems have shown themselves.

    So if i may ask for your patients, as soon as i get the chance to try the
    advise given to me, i'll report straight back.

    Kind regards

    Hello Members, thanks for hanging on, i've just tried installing the update
    with all the McAfee Security Center componets turned off, and the
    installation 'Failed', this also occured through the usual Vista Windows
    Update process, with McAfee off.

    But to answer the question related to whether i could download, and install
    any other updates through Windows update, there were 2 others today (Time
    8:40pm uk), and they whent through no problems, so can i prosume Vista
    Windows update service is ok?, and that it's related to something else?

    What is the next step?, should i contact Dell or Microsoft, or just ignore
    it and hope it corrects itself one day over future updating.

    I have looked over the web relating to this problem, and there seems to be
    alot of issues regarding this particular update, someone metioned something
    regarding when they had to restore to a previous registry version, this was
    for someother reason, and found it then installed.

    If anyone has a solution, i'd be greatful to know of it, i'm also going to
    go through the Microsoft free support service, see they have an answer.

    But as i've said previously, the computer runs great, so, if the solution
    seemed risky, a re-installation say, i don't think i'd do it.

    kind regards

    Thanks PA Bear, i've done just that, so now i have a Vista windows support
    reference, thanks for all yours, and eveyone elses help.

    I think it may end up being one of those, leave it to repair itself
    situations, one day suddenly it's gone events, through some other computer
    system change maybe.

    I only use Windows Live mail, and not the Outlook Express replacement
    Windows Mail, so i guessing this update is related to this email client, as i
    don't have MS Office Outlook installed.

    Thanks again, i'll update this post if MS have a working solution that
    doesn't involve re-installing the OS, which i don't think i'd do

    Hello Members, just to give a further update, i went through the free
    Microsoft Support service with no success.

    The two suggestions were from them are below....

    Please try the steps given below to resolve your issue.

    We have found that, this issue may occur, if any 'Third Party Software' is
    conflicting with the Windows Update Site. If you have 'Norton', 'McAfee' or
    any other Antivirus or firewall software installed on your system, the 'Third
    Party Software' can conflict with the Windows Update Site, hence I would
    request you to kindly disable these software, while accessing the site, this
    should resolve the issue for you. Please remember to enable the 'Windows
    Firewall' on your internet connection (if it is not already) before going
    online in case of virus problems.

    If the issue persists, let's go to the second suggestion.


    Rename Software Distribution folder:

    1. Click on 'Start', in 'Search', type in CMD and right click on 'Command
    Prompt' and click on 'Run as Administrator'.
    2. Type NET STOP WUAUSERV and press 'Enter'. (Leave this window open for
    later use)
    3. Open 'My Computer'.
    4. Find the folder c:\Windows\SoftwareDistribution.
    5. Right mouse click on SoftwareDistribution and choose 'Rename', call the
    folder "SDold"
    6. Return to the black Window that opened in step 1 type NET START WUAUSERV
    and click 'Enter'.
    7. Close all the windows.

    Once we have performed the above steps, please access the Windows Update
    site and check, if the issue is resolved.

    If the issue still persists, please provide me with the following
    information, so that the issue could be resolved more effectively

    Which i then did........, and received the response below.......

    Thank you for your response and providing the valuable information.
    I appreciate the time you have invested in following my steps. I am sorry to
    know that, they did not resolve the issue.

    Run the System File Checker tool

    To determine whether the issue that you are experiencing is caused by one or
    more system files that are used by Windows Vista, run the System File Checker
    tool. The System File Checker tool scans system files and replaces incorrect
    versions of the system files by using the correct versions.

    To run the System File Checker tool, follow these steps:

    1. Click Start, and then type cmd in the Start Search box.
    2.Right-click cmd in the Programs list and then click Run as administrator.

    If you are prompted for an administrator password or for confirmation, type
    your password or click Continue.

    3.At the command prompt, type the following line, and then press ENTER:

    sfc /scannow

    After the scan is completed it will give you information about the corrupted
    files in the system. If there are corrupted files then please do the

    Your best option here for this particular issue would be to contact the main
    Microsoft helpline: 0870 6010 100 (Hours of operation: Monday - Friday 8:00
    AM - 6:00 PM).
    And ask for Microsoft Windows VISTA Support, and I am sure they would be in
    a much better position to help you with your issue.

    So i did the sfc process, but still the KB905866 failed.

    So i guess, i will have two wait for it to rectify itself

    Kind regards
