  • Office updates fail. Error code 80070643

    Hi, I had a reo-ccurence of an old problem. Windows Update fails on the Office security updates. Error code 80070643.

    The modules that are 921598, 943973, 945185, 975051, 974554, 953404, 951535, 972580, 947319. Other modues installation ok.

    I tried to uninstall Office 2003 and reinstall. I tried checking DARE. EXE as suggested. PatchREgCleanup x 64 (for my Windows 7, 64-bit) will fail with a message saying "a product mus be determined." I tried Disabaliung and restart Windows Installer in the management of the computer.

    Whate otherwise I can do? Thank you.


    Thank you.

    The problem is now resolved. The flaw lies in the installation of FrontPage 2003. Security updates are installing.
    For the benefit of third parties who may read this page, I add the following observations: -.
    After the failure of an update there was little indication of the origin of the problem.
    However it happened to me that reliability monitor has given more information, for example
    "Windows Installer reconfigured the product. Product name: Microsoft Office FrontPage 2003. Product version: 11.0.8173.0. Product language: 1033. Manufacturer: Microsoft Corporation. Status of success or error of reconfiguration: 1603. »
    Then, I realized that all re - install the suite Office 2003 does not automatically re - installed FrontPage.
    It seems that when looking for this kind of problems, a check of the history of reliability could be useful to determine just where the problems come from.
    Thank you.

    Update KB982158 error 80070643___
    Hi - I'm under Win7 pro with Office 2010 - new brand Toshiba, so not old stuff to get in the way. I tried everything to get the Power Point KB982158 update to load, but get the error code 80070643. Well, I hope that I have tried everything!

    What does work is: try to install manually. unloading and reloading PPt and try to update; tried the 'Fix - it' KB suggested for a similar problem (error different message -0 x 80070646); tried to check the registry keys according to http://social.answers.microsoft.com/Forums/en-US/vistawu/thread/18449f60-c149-4eaf-b8e6-a2880cd7232b - the first two hits are as they are supposed to be, but under local_machine etc. There is no AppData, there is a CommonAppData whose value is % ProgramData

    should I change the value of %userprofile%\AppData\Roaming?

    or I'm far from base, is there another solution? afraid to touch anything without the advice of expert-thank you

    Hello

    You upgrade to Office 2010 or did you do a fresh install?

    KB982158 is an update of security for Microsoft Office PowerPoint 2007. As you have already installed Office 2010, you don't need this update.
    I suggest you remove all components of Office 2007 from the computer, including add-ins for Office 2007 from the control panel
    and see if that fixes the problem.

    Follow these steps:
    1. Click Start, then Control Panel.
    2. click on programs or features.
    From here you can remove office 2007 and its components.

    Hi John,.

    I don't know if you have tried to recover your system or not due to problems with Windows Update. You might be able to try a system restore and see if you can go back to before you have problems with Windows Update.

    Error code 80070643 is a generic error that basically indicate that an error has been detected by Windows Installer.

    Mark is right to say that you seem to have more problems than only with Windows Update.
    However, you might want to look at the following article to see if this will help with the error 80070643.

    Hello

    You are unable to download the updates?

    Try the following steps to resolve the problem:

    Method 1: Temporarily disable any security (including firewalls) software and check if the problem persists.

    Check out these links:
    http://Windows.Microsoft.com/en-us/Windows7/turn-Windows-Firewall-on-or-off

    http://Windows.Microsoft.com/en-us/Windows7/disable-antivirus-software

    If disabling the security software solves the problem, then contact the manufacturer of the specific security software to fix the problem.

    Important: 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:
