  I can not install the following Windows updates:

  Update of security for Microsoft Office System 2007 (KB976321)
  Update to filter junk e-mail in Microsoft Office Outlook 2007 (KB981726)

  The error message is: Code 646

  What the F?

  Someone please give me a solution.

  Greetings,

  Sorry, you have problems getting your patches installed. I have a number of things for you to look at.  First of all, your Background Intelligent Transfer Services set to Automaticand started and Windows Update ? They both should be started. You can check these settings by typing services.msc in the search box of the start menu.

  Sometimes in order to get patches to install correctly, you must perform these tasks manually. Click on each link below then choose download and run.

  KB976321

  KB981726

  If this does not work, try to run the Microsoft OneCare safety scanner.  Sometimes it will solve problems of hidden registry, or can clear the virus that can prevent the installation of the patches: http://onecare.live.com/site/en-us/center/whatsnew.htm. Click full service scan, and then Quick scan (full scan takes a long time to complete). Try the patches.

  OK... I had the same problem with the download of the 2007 Microsoft security updates. When I tried to install updates, I receive error 646. I finally solved my problem by going to the Download Center on Microsoft and I install manually.

  Here are the steps that I took... which I think should work:

  (1) go to the Microsoft Download Center: http://www.microsoft.com/downloads/en/default.aspx
  (2) look for each update code that begins with the letters "KB" and followed by a set of numbers (i.e. KB974234)
  3) click on the link for the download and then click on download and run. I think you have to accept an agreement, then click on continue or OK
  4) repeat for all downloads that you can not install
  (5) run Microsoft Update new and click search the updates and if updates have been installed successfully, they should no longer appear in the updates that must be installed.

  I don't know if it is not relevant or if it helped me succeed to install updates manually, but before I manually installed my updates I followed the instructions David_O posted here http://social.answers.microsoft.com/Forums/en-US/vistawu/thread/f3390e74-9961-4aae-8a05-554c1a9cf1a2 . I suggest that first of all try to download manually by following my directions. If it does not, then it's a possibility instructions of David resolved an issue that allowed me to download them manually disable Microsoft downloads site.

  I can't believe all the research and the suggestions of the technicians did not work... sometimes your own research is the best!

  I hope this helps! Good luck!
