    There are a lot of users having these problems. One solution is IF you
    have accepted the license (try to go back and answer YES if you don´t
    have done that, it`s easy to miss) -check out all questions/You maybe
    have to go back & activate (under resource for example)something in a
    new program you have recently installed) OR running low on diskspace
    -Try to remove the latest security updates, run cleanup and
    discfragment. Restart & try to update again. Kathe

    Yes - the conspiracy theorists have already come out.

    Problem is that manyhave pushed the updates you are having issues with to
    1000's of machines already. I did not have trouble on any of my personal
    machines and I know many people who did not have problems with these updates
    on their personal machines.

    Something is wrong with *your* machine and a percentage of other people. So
    far - the problem has not had a universal resolution, so the 'something
    wrong' is different on a few levels/in a few ways.

    Third party software changes, bum OEM installs, etc - who knows. But the
    fact remains that you could run Windows XP until you bore of it. You don't
    even have to update if you don't want to - I mean - you do know there are
    still people running Windows 98 out there, right?

    I've been having same problem and tried all the above--updates are
    downloaded, but installation always fails with the 646 error message...any
    new ideas?

    Manually download/installation means you visit the actual KB###### article
    page for each and download the appropriate file to your system (save it so
    you can double-click and run it later) and then reboot and install each one
    individually - perhaps rebooting after you install each one successfully.
    (sub in the appropriate ###### for each one)

    Then visit the IT professional's page, find the appropriate file for your
    system (office version, OS, etc) and click on that download link, save the
    faile for running later, reboot after you have them all.

    Log in as a user with administrative rights and if it is a Windows
    Vista/Windows 7 machine - right-click and run as administrator for the first
    update. I'd personally reboot after each one and before doing the next
    one - but I *know* that is overkill.

    I am using MS Office 2002 on Vista. I received two updates: one for Word
    2002 and one for Excel 2002. Both of the updates would not install and
    indicated Error Code 646. I tried all of the suggestions found here with no
    luck until I applied all of the suggestions (shut down firewall, open
    Outlook) and then also opened up Word and Excel and, probably most
    importantly, turned OFF the Administrator User Account Control (UAC), found
    at User Accounts, to allow changes to take place on the computer. The
    updates installed, I restarted the computer and all is well! I have
    encounted several situations where turning off the UAC allowed me to download
    and, at times, uninstall programs that otherwise I was not able to do. Vista
    works well, when you figure out how to navigate through it. Free MS tech
    support would be appreciated for MS system issues!

    hi, novice here. What does the UAC stand for? Thanks

    I tried the Micosoft Outlook open and the update did not work for me. Anyone
    with any other suggestions?

  12. Ladylost,

    Now is a great time to point you to one of the easiest ways to find
    information on problems you may be having and solutions others have found:

    Search using Google!
    (How-to: )


    A little deductive reasoning... You should see rather quickly - in this
    context - it likely means:
    User Account Control

    Hi there,

    I just solved my download problems for error 646, I've been having this
    problems for 2 months and nothings seem to help. Until I read one of the post
    in this forum that suggested that we try to download the optional download
    which I did and it works for me!

    You click on the review update and checked on the optional download and they
    will prompt u to accept the license agreement, checked that too. the optional
    download will be installed together with the important download. I hope this
    information is helpful to all of u who has the same problems as me.

    Go to start search type in MSCONFIG. click on tools then UAC. slide it down
    to "do not notify" then re-boot. try windows update again and it should work.
    I returned it to s normal settings and will see if I have to do this all the
    time. I hope not but at least this will help

    (11/21/09) - I have Vista (64bit version), and I was getting this error
    for three weeks myself. Thanks to one the suggestions below, I got it to
    work. The suggestion that worked for me was to "manually" install each
    update "individually". I could not use the windows automatic update
    feature. Here's what I did (BTW, I did not have to turn off my firewall
    to do this):

    1) Went to Bing.Com
    2) Typed in the exact name of the update as it was displayed on the
    Windows Update Screen (e.g. Security Update for Microsoft Office Excel
    3) Bing found the exact match to what I typed in on the Microsoft
    4) I clicked on the link
    5) Selected "Download"
    6) And Viola, it worked :)
    7) I repeated this step four more times, and now I've successfully
    installed all five updates that I'd been trying to install for three
    8) Thanks again to all of the tips people listed below, that was
    helpful and the "manual" update tip worked for me.

    Hope this works for other people as well.
