  Technical details:

  Error 0 x 80070646 or 646 is a MSI installer error that won't happen when the updates are installed via the Windows Update control panel.  Workaround solution previous to solve the immediate problem requires the installation of the update to a standalone package starting from Microsoft Download Center.  We do not recommend this workaround solution.

• Problems installation security for Microsoft Office System and all of the programs in the Microsoft Office System (error Code 646)

  I have a laptop running Windows 7 for x 64 bit. Whenever I try to install an update to security for Microsoft Office System2007 or any program that is, I get the error code 646. Everything else seems to be updated. It's really aggravating because when I will shut down my computer, I have to wait until the updates are installed before it stops, but then when I turn it back on and turn it off again, he always says I have to install the same updates to day when I finally stopped and I still have to wait until they are installed. It's a never-ending cycle. What the heck is wrong with Microsoft Office that makes it to where everyone seems to have the same problems? Don't you think that this problem must be corrected instead of simply suggest to download manually? Download manually takes too much time and honestly makes no sense. What is the point of having Windows Update if anyone seems to have manually make updates of Microsoft Office?

  Hi baby Deanna.

  Download the updates manually would let us know what update is causing the problem and that's when we suggest the user to try because it could limit the question.

  Mention updates with which you are having problems with.

  Step 1:
  I see that many users have encountered this problem and they were able to install the updates successfully by disabling the User Account Control [UAC].

  First disable user account control before installing updates.

  Access the link for more information below how to turn user account control on or off:

  http://Windows.Microsoft.com/en-AU/Windows7/turn-user-account-control-on-or-off

  Note: Enable UAC once the diagnosis is made.

  Step 2:
  If you still experience the problem, run utility of Windows update that might help us diagnose the problem better.

  Access the link for more information about the Windows Update troubleshooting tool below:

  We look forward to hearing from you.

  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!
