  • 07/12&13/2007 same problem and tried several fixes.  If misery loves company then we will have to wait until enough users let MS know so they will fix the problem.

  • I have the same issue and just came across this post.  Scroll down to Chris Rowat's answer which apparently worked for several of the members.  I haven't tried it since I just came across it.  Good luck.

    Restart your computer before you go back to the Update page.

    I have a computer that is less than a year old, and "Uniblue" tells me I have to "Purchase" because "they" found over 900 "errors", and I just had it cleaned at Staples...

  • Hi, After digging around for an answer, like remove all versions of .net etc, I found that if I tried to remove them or if I tried to install the update manually from an independent download, I was given error about not being able to find drive x . As drive x didn't exist, I plugged in a usb stick. Assigned it driver letter x and re-ran the .net update from Windows Updates. Voila!

    I hope this helps somebody.

  • This is a bit late lol :-) in coming but i have been having a problem downloading important security updates but i found out how to fix the problem for a user on here. Here is what she suggested.    The solution is to turn your UAC (user account control) off. Go to control panel and in the "search" bar type in uac.  Turn it off and restart the computer. Then do the update and turn the uac back on. Hope this helps.    It worked!! Btw, i'm a newbie :-)

  • Mr Prophetline is right on!  I simply uninstalled the .NET1.1 then did the windows update and it worked perfectly.  Unfortunately I believed another one of you and bought RegistryBooster and I'm sure it is good but it didn't fix the problem.  Mr Prophetline rocks!

  • I try this one and it works for me..

    1. Click Start

    2. Click Control Panel

    3. Switch to classic view in upper left hand corner

    4. Double Click Programs and Features

    5. Find Microsoft .NET Framework 1.1 and highlight it

    6. At the top choose Uninstall/Change

    7. Click the radio button labeled Repair (it is clicked by default)

    8. Click Next

    9. Let the repair run

    10. Reboot

    11. Re-run the update

  • how would you let you know ms about this error?
    Monday, October 11, 2010 7:16 PM
  • I followed your directions that you have posted, but I think I ran into a problem when I chose to Uninstall/Change the file Microsoft .NET Framework 1.1 it didn't give me the chioce to repair it or change it. When I push the tab it automatically Uninstalled that file from my computer. When I rebooted my computer to run the update again it said the undate wasn't needed. So my question is now did something go wrong and if so where can I go to download Microsoft .NET Framework 1.1 again??

  • I was trying to install updates to a friends laptop (Vista.... arrgghh), when I encountered a problem with the .Net framework 1.1 sp1 that wouldn't install. I got the error message 643. After trying & trying agian to install it, I then went to Google to research the issue. There were so many posts that insisted on uninstalling & reinstalling all of the .Net Frameworks, I was just ready to pull my hair out. I really didn't want to have to spend hours going through something that may or may not work. Then I came along this post & thought: "Sounds to easy to be true, but I'll try it first before the un/re installing"

    Bam it worked!!! Yippie!!

    ** (This is a step by step for newbies, for those a bit more advanced just follow the above post's instructions) **

    In windows Vista:

    Open: Control Panel from the Start Button

    Then: In the top right hand corner of the window, there is a search box:

    Click in the text field and type the letters:     uac

    You will then see in the main part of the window "User Accounts"

    Under that, use your cursor and highlight the words below User Accounts

    "Turn User Account Control (UAC) on or off"

    Click on the link.

    Then you will see on the next page:

    'Turn Off (maybe the word on) User Account Control to make your computer more secure

    User Account Control (UAC) can help prevent unauthorized changes to your computer. We recommend that you leave UAC turned on to help protect your computer.

    [] Use User Account Control (UAC) to help protect your computer.'

    The box above will have a checkmark in in indicating that it is turned on.

    Now: Uncheck that box

    And click OK

    Next:

    Restart the computer then,

    Go back to the Windows Update and try to install the .Net Framework update.

    It most likely will work, it did for me (Whew!!)

    Be sure to restart when the update is complete!

    Then go back to:

    Open: Control Panel from the Start Button

    Then: In the top right hand corner of the window, there is a search box:

    Click in the text field and type the letters:     uac

    You will then see in the main part of the window "User Accounts"

    Under that, use your cursor and highlight the words below User Accounts

    "Turn User Account Control (UAC) on or off"

    Click on the link.

    Then you will see on the next page:

    'Turn Off (maybe the word on) User Account Control to make your computer more secure

    User Account Control (UAC) can help prevent unauthorized changes to your computer. We recommend that you leave UAC turned on to help protect your computer.

    [] Use User Account Control (UAC) to help protect your computer"

    In the box above click on it to replace the checkmark.

    This will then turn it back on.

    And restart the computer!

    Problem fixed! :)

  • I had the same problem and it was too complicated for me to understand but I have Advanced windows care and I did a deep scan and it fixed the problem for me. You can download Advanced System Care from Cnet as it is very good and sorts things out that I do not understand as I am no techno gheek!!! When you download it do a deep scan and under the vulnerability scan you will see that it notices the latest updates are not downloaded and it will fix it for you. I then checked windows update again and everything was up to date. I hope this helps as I was working at it for hours and getting nowhere!

  • trying to installed windows updates for service back .net 1.1 on Vista Ultimate and keep getting error code 643.   tried everything i could find (adobe fix, windows installer etc..) and nothing.  anybody got anything new?

    After numerous attempts trying other avenues, I did what some did below & this finally worked. Do NOT uninstall anything--unneccessary.

    Go to start & in the search bar type user accounts (sometimes all is needed is uac) then click on user accounts in the main search bar to the left under "programs". Look for "turn user account control on or off" & click on it. It will ask if you want to continue or cancel--click continue. It will give a warning that it is not recommended--but not to worry. It will show a box that is checked already--click the box to uncheck it & then restart your computer. When computer reboots, go to start, control panel (right side) & find windows update. Select updates needed & begin the update process. After installation of updates, restart computer. Go back to start, & pull up user accounts again & repeat the process to check the box to turn the user account control back on. Restart. All of this may take about 10-15 minutes MAX. It also works! Good luck

  • This fix worked for me as well.  Click on User Account Controls and Family Safety and then click on User Account Controls.  Then click on User Account Controls on or off.  Then uncheck the box "UAC to help protect your computer".  Restart computer, apply the update that was not installing, then restart computer once again, repeat User Account Control as above and recheck the box "UAC to help protect your computer".  Do the final restart after this step and you should be good to go.

  • Go to the control panel to UNINSTALL PROGRAMS; find the Microsoft.NET file and click to uninstall--It will ask you want to FIX or UNINSTALL.  Select fix--this will take a few moments. Restart, and it should go away.

     

    Hope it works.

  • Hi,

    The Windows update error code 643 in Windows 7 Operating System could be resolved by the two methods.

    The first one is to fix the MSI software update registration corruption issues.

    For this you have to first confirm whether the product is affected or not.

    Then you have to re-create software update cache registry details and should delete the remaining software update references.

    If the problem is not solved then, you are advised to repair the .NET Framework using the .NET Framework Cleanup Tool.

    Get more information to fix error code 643 :

    http://supportformicrosoft.iyogi.com/windows-7/windows-7-error-code-643.html

    Hope this information helps you.
