    I've been trying to install the latest .net auto-update for about a week, and
    it keeps failing. The history log says error code: 0x643, about which there
    is nothing in the knowledge base.

    Security Update for Microsoft .NET Framework, Version 2.0 (KB917283)

    Help! What's happening?

  2. Search this newsgroup for 917283 for suggestions.

    Or try this:

    The following is a revised version of an earlier post by TKang:

    Note:
    a. Some ATI VGA users may need to disable/exit the Catalyst Control Center
    (which uses .NET) before updating the framework.
    b. Users of Windows Live OneCare must disable that application before
    removing or updating the Framework.

    1: Turn automatic updates off.

    2: Download .NET 2.0 (for 32-Bit) at this link:
    http://www.microsoft.com/downloads/...cb-4362-4b0d-8edd-aab15c5e04f5&displaylang=en

    OR

    2a: Download .NET 2.0 (for 64-Bit) at this link:
    http://www.microsoft.com/downloads/...00-ACF8-4FA1-AFFB-40E78D788B00&displaylang=en

    3: Use control panel Add/Remove Programs to uninstall Microsoft .NET
    Framework, Version 2.0 and reboot. Do not touch .NET Framework 1.1.

    3a: see note below at step 7.

    4: Install Microsoft .NET Framework, Version 2.0 (for 32-bit: dotnetfx.exe
    3/22/2006) or (for 64-bit: NetFx64.exe 3/30/2006) and reboot.

    5: Then run MS Update (and install KB917283) then reboot.

    6: Turn automatic updates on (assuming that is your preference).

    7. If this procedure failed to allow update 917283 to work, then repeat the
    procedure, adding the following at step 3a:
    Download http://astebner.sts.winisp.net/Tools/dotnetfx_cleanup_tool.zip and
    unzip it. Run the enclosed application, and select to clean up .NET
    Framework 2.0. Now continue above from step 4.
