    Windows update error code 66A

    When I try to install the update for .NET Framework 1.1, Service Pack 1 I get
    an error code 66A. I have searched for a resolution but can not find one.
    What can I do to resolve this?

    Re: Windows update error code 66A

    Which Version of Windows is installed ?

    IF .NET Framework 1.1 is showing as installed in Add/Remove Programs in
    the Control Panel, suggest you download SP1 from here and save it:
    http://www.microsoft.com/downloads/d...DisplayLang=en

    When the download completes close all open browsers and programs.
    Now install NDP1.1sp1-KB867460-X86.exe and restart the system.
    Did that get it installed ?

    <cmd_output OS="XPsp2">
    F:\>set /a c = 0x66A
    1642
    F:\>net helpmsg %c%

    The upgrade patch cannot be installed by the Windows Installer service
    because the program to be upgraded may be missing, or the upgrade patch
    may update a different version of the program. Verify that the program to be
    upgraded exists on your computer and that you have the correct upgrade
    patch.

    </cmd_output>

    At least the code gives you something to try... <eg>

    Do the logs give you any better clues? Hint: search for context
    for the hex string and its decimal equivalent.


    Good luck

    Download the update manually and install it from the previously provided
    link. That has worked for others in the same situation as you are now in.

    OR, you can stop the Windows Update service, delete the previously
    download of the update located in
    SoftwareDistribution\Download\Install
    Restart the Windows Update service, and then wait until the fixed
    version of the update is downloaded.

    I'm not a computer genius, but I have followed the posted directions. The
    message up above is what popped up when my computer tried to install the
    file, and I am at a loss. I've only had this for 2 months. Any help would be
    much appreciated.

    My follow-up question is whether or not you need to have .Net Framework 1.1
    if 2.0 is installed

    Re: Windows update error code 66A

    ..NET Framework 1.1. and 2.0 run side by side and are not dependent on
    each other.
    BUT, if a Program was installed that requires either Framework so that
    it can run, then the answer is yes.

    It gets more complicated with the installation of 3.0
    That requires that 2.0 be installed, also.

    Clear as mud, eh ? <w>

    Re: Windows update error code 66A

    I have problems installing the
    "update for visual studio 2005 service pack 1 (windows vista)"
    and the
    "safetyupdate for microsoft visual studio 2005 service pack 1(KB937061)"
    It always says "error code 66A".

    Previously I tried to install "Visual Studio 2005 service pack 1", but it
    always failed, so it's very logical that I can't install the update to the
    service pack since I don't even have the service pack....

    But when I check the installed updates, the service pack 1 is in there...
    even tough it ALWAYS failed to install. And the windows update doesn't
    recognize the service pack 1 as a new update anymore, since it 'should' be
    installed...
    How can I resolve this problem?

    RE: Windows update error code 66A

    The steps you need to follow are:

    1) Run cleanup tool:
    http://astebner.sts.winisp.net/Tools...eanup_tool.zip

    and select remove (cleanup) .NET Framework 1.1 from the dropdown list.

    2) Download the .Net framework 1.1 redistributable package from her
    http://www.microsoft.com/downloads/d...7-034d1e7cf3a3

    and install it.

    4) Download the .Net Framework 1.1 Service Pack
    https://www.microsoft.com/downloads/...displaylang=en
    and install it.

    5) Instead of using Windows Update, download the KB929729 package from here
    http://www.microsoft.com/downloads/d...displaylang=en

    Install this Last!


    I followed the steps and the his windows update looks much healthier now

    Hope this helps!

    RE: Windows update error code 66A

    MS if continuing it's track record of lousy support. I'm on a one week old
    HP Computer with Vista Ultimate on it and today was told by "update" that I
    need to install a Framework update. It will not install and comes back with
    an error code of 66A which as is typical of MS and tells me nothing. A brand
    new computer, no registry changes have been made, all updates save this one
    have been installed when the flag went up to install them (sorry, didn't
    install the 35 various language updates). My old computer with XP MCE
    encountered the same problems with trying to install updates to Framework and
    I spent weeks trying to get the updates installed. Thanks to Aaron Stebner
    (sp?) finally got it straightened out, but not without many messages back and
    forth. I don't see how MS can blame this problem on users messing up
    machines, installs, etc. since this is a brand new machine, unadulterated
    OS, running MS Vista Ultimate (not an upgrade version but a full blown copy
    at $$$$$).
    MS -- what is your defense?

    Did you reinstall the OS yourself or did it come preinstalled from HP? Have you
    and/or HP installed any applications on the computer yet?
