    Running : Windows XP media center edition SP3
    Have tried installing KB979906 a few times and also downloaded update
    manually but cannot install this update. Receiving error 0x643.Is it safe to
    uninstall the .NET Framework 1.1 and re-install as possibly corrupt , without
    having to uninstall/re-install all other .NET frameworks 2 , 3 and 3.5
    including the updates that go with them? ..

  3. First run the Fix It in this KB article & see if the update will install
    after doing so:

    How to fix MSI software update registration corruption issues

    If no joy, see...

    When installing updates using Windows update or Microsoft Update you may
    receive Error 0x643 or 0x80070643 (23 Oct-09)

    Then proceed per the following:


    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

    Step #2 => Now see Resolution Method 2 in this related KB article:

    After running the .NET Framework Cleanup Tool (not the Windows Installer
    Cleanup utility!), reinstall 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: Please read
    ALL of it as well as the related page before using the .NET
    Framework Cleanup Tool.

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

    Thanks for info..Followed link and used repair tool for .NET Framework then
    tried to re-install update with no success.I took a chance and just
    un-installed the .NET 1.1 framework from add/remove programmes which also
    removed all the previous 1.1 Framework fixes with it.I then re-installed it
    via wndows updates with success.I restarted computer and then checked for
    windows updates as normal which included KB979906 and it installed perfectly
    without any errors.The earlier hotfixes did not appear as necessary updates
    so i can only imagine they are now no longer required as KB979906 perhaps
    incorporates all necessary fixes but i am only guessing.
    Luckily i did not have to uninstall all other .NET frameworks 2 , 3 and
    3.5 and reinstall them which would be a long process but the quick
    alternative worked ok for me (so far)....

  5. Same thing happened when we tried to update. 2 people updated, 2 people .Net
    not working.

    It seems these two are causing the problems:


    We are refraining from updating the rest of the computers until we know
    what's going on.
    TruckerHarley, Jun 9, 2010
  6. What's going on is that the updates aren't installing on the 2 computers.
    Who knows why but only you can fix it.

    See my previous reply or...

    See the "How to obtain help" section of, e.g.,

    For home users, no-charge support is available by calling 1-866-PCSAFETY
    (1-866-727-2338; and/or 1-866-234-6020 and/or 1-800-936-5700) in the United
    States and in Canada or by contacting your local Microsoft subsidiary.
    There is no-charge for support calls that are associated with security
    updates. When you call, clearly state that your problem is related to a
    Security Update and cite the update's KB number (e.g., KB979909).

  7. It's .net. They barf. Their "servicing" process sucks. There's no way
    to predict what machines may have patching issues or not. You just have
    to be ready when .NET has updates.

    Thanks for this cogent method to solve the problem. This was the first time I
    have had a problem with a MS Update (KB979906).

    It took nearly two hours to fix the darn thing, but it DID work.

    As I was removing all of the .NET Framework pieces manually, I noticed that
    the ADD/REMOVE programs screen from the control panel indicated that NONE of
    these programs had ever been used since they were installed. If that
    information is accurate, I am wondering why I have this stuff installed in
    the first place!

    Programs and applications that were installed by the OEM or you have
    installed require the .NET Framework in order for them to function.
    ATI's Catalyst Control Center and Quicken are 2 such apps/programs
    amongst many others.

  15. That fix method will only make matters worse if .NET Framework 3.5 (SP1) is
    installed & removed!

    Had to run this same scenario last October for KB953297. It gets irritating
    to have to run this time consuming fix again in less than 1 year. Would like
    to underline the word irritating.

    I run a network of over 200 machines and use WSUS to deploy our
    Windows/Microsoft patches. Since patch tuesday (2 days ago) kb979906
    kb979909 were approved and sent out to all machines.

    We now have 68 (and increasing) machines all showing errors trying to
    install those two patches!!

    A full removal of .net is simply not an option so this is very
    frustrating - I'll watch this thread with interest...

    Hi j: I started this thread looking for an answer and although i recommend
    PA BEAR [MS MVP]'s solution of complete removal and intallation of all the
    ..NET Frameworks in correct prescibed order as being safest method, i took a
    risky shortcut (as i always do) and just uninstalled the .NET 1.1 Framework
    alone and then just reinstalled it again as i am a bit lazy.I was very
    pleased when i checked for updates the problem KB979906 was there and
    installed perfectly without a hitch.I have had no problems since then
    (although it is early days). I think the problem is that the .NET 1.1
    Framework has become corrupt with all the fixes and patches so a simple
    re-installation does the trick.
    I hope you could maybe try this as an option for all your computers but
    don't blame me if it is unsuccessful. I am practical but no computer buff. It
    is worth a try though if your only other alternative is complete removal /
    re-installation of all .NETs. on all 200 machines. cheers S...omes

    I'm afraid that solution won't work for me. I've had my machine for less than
    two years from Dell and it's the second time it's had this corruption - the
    only way to fix it was to backup my stuff and reinstall everything...

    I suspect this problem is never really going to go away, simply because it's
    the way Dell fiddle with the OS so their hardware can work! Isn't there just
    a simple direct-download link for this file like everything else?
