    Error 643 - KB973688 & KB976098

    Have Windows 7 Ultimate 64bit and just in the last 1 week has these two
    updates started to fail. have read the other comments with regard to error
    code 643 but none of the responses seem to apply to Windows 7

    I have all the .NET frameworks installed and they came ready with the desktop.

    Any ideas on how to successfully install these updates and has anyone else
    experienced this problem?

    I am having the exact same problem KB976098 but I have Vista Ultimate.
    This has been the only one I haven't been able to install through
    automatic update OR using the stand alone installer and trying to do it
    manually.

    Your post was the reason i signed up here. I have been searching
    relentlessly since yesterday morning for a solution and I still can't
    figure this out.

    Did you upgrade to Win7 or is it a brand-new computer with Win7
    preinstalled?

    When installing updates using Windows update or Microsoft Update you may
    receive Error 0x643 or 0x80070643 (23 Oct-09)
    http://support.microsoft.com/kb/976982

    =====================

    Step #1 => Before doing anything else, write down what .NET Framework
    versions are currently installed:

    How to determine which versions of the .NET Framework are installed and
    whether service packs have been applied
    http://support.microsoft.com/kb/318785

    Step #2 => Now see Resolution Method 2 in...

    When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0,
    or 3.5, you may receive Windows Update error code "0x643" or Windows
    Installer error code "1603" (ignore the title, if need be)
    http://support.microsoft.com/kb/923100

    After running the appropriate/needed tool, (re)install all .NET Framework
    versions (but only the ones you wrote down in #1 above) manually using the
    download links on the page then run Windows Update manually to install
    security updates for same.

    NB: If you remove .NET Framework 3.5 SP1 using the tool, reinstalling .NET
    Framework 3.5 will also install .Net Framework 2.0 SP2 and 3.0 SP2; then
    Windows Update will offer .NET Framework 3.5 SP1.

    IMPORTANT! => If you remove .NET Framework 3.5 SP1, reinstall your .NET
    Framework versions in the following order:

    1. .Net Framework 3.5, then...
    2. .Net Framework 1.1, then...
    3. .Net Framework 1.1 SP1

    NB: KB923100 references this page:
    http://blogs.msdn.com/astebner/archi...30/611355.aspx. Please read
    ALL of it as well as the related page
    http://blogs.msdn.com/astebner/pages/8904493.aspx before using the .NET
    Framework Cleanup Tool.

    Step #3 => Check-in at Windows Update and install any critical security
    updates offered.

    Download the update from here to your system, right-click the installer,
    choose Run as Administrator. You may get an error still, but you will be
    able to ignore it
