    Hello

    Here's what I recommend you do:

    1. disable UAC (do this if you are using Vista or Windows 7, otherwise, go to step # 2). Comes down

    restrictions - turn it off completely.
    2 restart your computer for the change to take effect.
    3 re - download the update of security for Microsoft Office System 2007 (KB982331) from the link below:
    http://www.Microsoft.com/downloads/details.aspx?FamilyId=7f89a734-cda4-4abb-9a10-f6dfe560e8d0&displaylang=en
    4. install. It should work fine.
    5. If it still does not work, try to open all or part of your MS Office applications (such as MS Word, MS Excel, etc.).
    6. follow steps 3-4.
    7. If it still does not work, follow step # 3 again. After you download it, try unplugging your computer from

    Internet (unplug the internet cable or turn off the modem). Then, try to install the downloaded file

    (KB982331). It should work this time.

    Do the same for all the updates that come with KB982331, IF ANY.
    Let me know your results.

  • Failed to update security for Microsoft Office 2003 (KB2584052)

    I have six updates to security for Microsoft Office 2003 that is (KB2584052) and they always fail.

    Any advice?

    Hi SteveGjorkes,

    ·         Do you receive an error message/code?

    ·         Did you do changes on the computer before the show?

    ·         You are able to install some other updates without any problems?

    Before windows updates, follow these methods.

    Method 1: Temporarily disable the security software.

    Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

    Method 2: Restart the computer in a clean boot state to see if there is a software conflict as the clean boot helps eliminate software conflicts.

  • Impossible to solve problems with the update of security for Microsoft NET. Framework SP1 (KB2657424)

    I hope that Microsoft Support will answer this question:

    Homepage of Microsoft Windows Update is re - download and reinstall the same update (KB2657424).

    I was advised to try this link: https://support.microsoft.com/oas/default.aspx?gprid=6527 and it brought me to this page.

    I downloaded Microsoft Fixit 50202, installed and ran, but in "default" mode, since he warned that "aggressive mode" may disrupt other updates.

    It took me 8 hours (using a dial-up access provider) to get through all of the suggestions, including those in the following links:

    http://support.Microsoft.com/kb/910339

    http://support.Microsoft.com/kb/906602

    http://support.Microsoft.com/kb/2657424

    http://www.Microsoft.com/download/en/default.aspx

    I followed the suggestion of Microsoft to visit their site and check out "Review of my update history". Since January 11, 2012, when Microsoft first downloaded the update to in question (KB2657424), it failed. Microsoft has offered by clicking on the Red 'x' next to the 'update failed' to open the info on the reason that has been...

    Error code: 0x01

    Microsoft proposed the search for this error code in this list:

    http://support.Microsoft.com/ph/6527

    The error code is not in this list.

    Microsoft said then click "find solutions," "enter keywords" and click on "search". The result was this message: "Sorry, no result found not to match this criterion."

    As I mentioned earlier, since the first update "failed", I clicked several times on the icon (almost daily), which reappears constantly in my taskbar, asking me to "Reinstall", the update, and these measures have been recorded at yellow end of Microsoft. As I mentioned earlier, the update of security (KB2657424) is already listed in my Add/Remove programs as being installed. The "update history" reveals that a series of 'success' (KB2657424) facilities are recorded as well as "failures".

    I went to Windows Update Microsoft Web page to 'review my update history'.  After analysis of my PC, Microsoft has determined that (KB2657424) "has been downloaded and ready to install," with another update of IE (KB2618444). So I clicked both for "Quick Installation".

    When you are finished, I revisited the "update history review". (KB2657424) has been disabled with the green icon as 'successful', while at the same time, in the right box next, there was a message: "Install Updates (1).» So I clicked it, and another window open with the message that the "high priority update" (KB2657424) had to be installed. Yet once, I clicked on "Install updates". He ended with another successful window "Update."

    Then I clicked to "review update history", and it was registered under the name "successful." But the window beside her reappears at the same time: "Install Updates (1).» I have has. ... It was the 3rd time within an hour. 3 slices of the same update (KB2657424) are now disabled with the green icon as "successful"... but the window side "House of Windows Update" reappeared again with the same message: "Install Updates (1).»

    Then I followed the suggestion of Microsoft to type in the "run command" keywords to the day windows journal. Since the January updates up until this date in February the journal is 428 pages (transferred from Notepad to Microsoft Word.)

    Then I followed the instructions to download the update 'NDP35SP1-KB2657424 - x 86 .exe' (1.3 MB) directly from Microsoft link... http://www.microsoft.com/download/en/details.aspx?...28569.

    As instructed, I proceeded to manually install it in "Safe Mode".

    The result was this message:

    Patch installation (c:\35b7019bd0df08ac0003ec93627c\NDP35SP1-KB2657424.msp) failed on product (Microsoft .NET Framework 3.5 SP1). MSI log: Microsoft .NET Framework 3.5 - KB2657424_20120209_020143359 - Msi0.txt

    I scanned the PC with anti-virus and anti-malware programs, and none of them found any malware or virus in the way of updates from Microsoft. "The 'update' where it is saved in the Microsoft Download link is the only and unique" ""NDP35SP1-KB2657424 - x 86 .exe." The "Update" as it is installed in my Add/Remove programs in the Control Panel is the same.

    However, both "Windows Update Home" to Microsoft Page as well as in my BONES, the "update" continues to override all commands of Windows. Another odd fact, is that this "update" that keeps re - download and reinstall itself is actually partitioned into three parts, and I wonder if they may be "clones". Maybe the Windows Installer Service does not know where to place them, or what to do with them. These are three:

    MSIPatchRegFix - X 86 .exe_

    NDP35SP1-KB2657424 - 86.exe_

    NDP35SP1-KB2657424 - 86.exeQ
