I can't install Windows Update. Error code 641

Hello!  I hope I'm posting in the right place.

I tried several times to install updates and nothing has worked.  The said tool fix fixed it and maybe he did because a few updates have been installed, but many were not.   I'm not very technical, but I'll try to explain in as much detail as possible.

I am running Vista Home Basic. It has Service Pack 2. The Type system is PC based X 86.

Get error codes on some 641 and 80070020 on others. As I said I'm not technical and maybe I don't know what I'm talking about, but I think that the computer is missing some critical files. For example, sometimes he said: the installer of Windows are not available. I don't know if I need that updates however. Finally, I tried the fix and he said: it has been fixed. I managed to install as 1 update, but most of them failed or if windows update said it was successful, when I restart updates have been configured wrong, so he returned changes. I disabled avast anti-virus & system guard (mechanic system) because I thought he could block and which seemed a little help I got an update installed.

I continue to look for solutions and try new things. I tried to download the Windows Installer 4.5 Redistributable. I think that windows6. 0-KB942288-v2-x 86.msu is the one that I want, but it continues to tell me that it does not apply to the computer. Choose one bad? It's Vista and x 86 (said information system). I've tried every solution I could find in the forums, but nothing works. I think something must be reinstalled, but I don't know what. If someone can tell me what to do?

    It of funny to me that I serve on 31 computers Windows update since 1998 and never had the first problem with Windows update, and yet I see many posts like yours here all the time. Did you accidentally made changes to the registry, or run Registry cleaners? I wish I knew this better, but anyhoo here are things that you can check.

    . Get your updated antivirus program and start safe mode. Note that some viruses can hide from your normal antivirus program, so you really need to scan mode without failure. To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode. Then run a complete system scan.

    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.

  • Cannot install Windows Update error code 80004002.

    OT:help: Windows Vista 64 problem (inaccessible update).

    Hi all

    Hope you can help me solve this problem.  I'm not a "dummy" computer in many ways, but please treat me as if I was a (do not assume I know that the process to follow to achieve your advice).  It will be easier because I won't have to ask, "you told me to do this, but I don't know how."

    We had this installed desktop (Dell Studio with Vista 64) for about 5 years computer.  A couple of days, I noticed that all of a sudden I could get are more updates of Windows (it is set to automatic, but sometimes I do it manually) and that the history of the update has been completely served.  I also noticed a problem with .zip files.  I can is more freely manipulate them, such as the addition of a text file or delete.  I suspect the problem with zip files is impossible to obtain the updates of Windows, but I am of course much concerned by the updates of Windows.  I rarely use zip files, and I have for countless alternatives for these issues.

    When I try to get the Windows updates, the error code 80004002 appears:

    I did some research and learned that it probably has to do with the lack of "Windows Service Pack 2".  I downloaded and tried to install SP2 several times, but each time I get this message:

    When I click «go online to learn more...» ', nothing happens.

    I should add that I do not have Service Pack 1, and I also ran a variety of malware and cleaning programs, all without success.

    If anyone can help me solve this problem, I would be very grateful.

    You're welcome, thank you for your feedback & good luck. Mark one or more of my previous posts as RESPONSE will officially close your thread.

    This can be a simple solution for some users.  If all Microsoft updates installed correctly on your computer except security updates and you run McAfee, remove McAfee.  Dell technical support who did for me and it works.

    Vinod,

    Thanks a lot for your comments. I am unable to give you the precise steps to solve my problem of 641, as the removal of McAfee - and general cleaning - was made by a Dell technician, using the GoToAssist company function, while I looked on. It doesn't seem to be a very complicated process.  In my view, that McAfee can guide you in its eradication program. Try it and let me know how you do.
