error 80070643, cannot install security essentials

I'm trying to install security essentials

The operation will fail with error code 80070643

I tried many patches assumed for this problem as shown on the boards

I run the microsoft Fixit utility, which said it corrects a problem with the updated engine but it still didn't solve the problem or allow installation of security essentials

I can't install this protection necessary virus at the moment

Problem solved... ran "OneCare" cleaning/removal... tool and then MSE installed without problems

  • Automatic updates do not. Discovered when trying to install Security Essentials.

    I have XP - Media Center Edition.  It has been updated to SP - 3 some time ago.  I've always used updates to power off, so I never see the process underway.

    I just uninstalled Norton 360 and that he would upgrade to MS Security Essentials, but Setup has failed.  I then googled the error code and found an article that said that it could be related to not having all the updates.  I went and manually start the automatic updates and I found it is bombed on.  Then I checked the log and found that it worked very well until an automatic update around September 17, 2009.  After this, almost all the automatic updates failed.  I never know what I used the update to the power down of the method.

    I found a post that says (Phase 1) stop the windows update routine and rename the folder "c:\Windows\SoftwareDistribution" and then restart the windows update routine.  Phase 2 was to force a reinstallation of Windows Update Agent.  I did these things and when I did an update, found that an update loaded for windows, but all other updates (for things like the Net.frame) and other applications, has failed.  Try to install Security Essentials also bombed.

    I looked through the forums and found that most of the people are referred to an article on whether you installed the SP3 before restarting after repair or installation of SP2.  This doesn't seem to be my problem.

    I hope that this story sounds familiar to someone who can guide me to a solution.  I still haven't yet installed virus protection program and really want to use the bulk of the security.

    Thanks for any help you can give,

    [1] the error Code is 0 x 80070643.

    As you change major versions (6-9), the complete installation program must be downloaded. Then, it must be verified and unpacked. Then to do room to write the new while the former is still partially around. He spells that require at least 6-7 GB of free space on the device for an Over The Air update to even have an inkling of a chance to succeed.

    If you do using the iTunes program on a Mac (favorite), download, verification and unpacking occurs in the computer (which has usually a lot more resources than the phone), reducing needs about 1 to 2 GB free space.

  • I installed Security Essentials and it causes Defender to stop the run.

    * Original title: Security Essentials

    I installed Security Essentials and it causes Defender to stop the run. The only way I can turn the Defender needs to restore my computer to before Security Essentials. I tried twice and got the same result.

    Security Essentials replaces the Defender?

    I am running Vista.

    Thanks Len H

    You are right.  MSE (Microsoft Security Essentials) in Windows XP, Vista and 7 can be used instead of Windows Defender.  They can not be activated at the same time.

    A google search of the proposed problem that there is an error related to the number of times I can reinstall this product due to licensing issues.

    Absolutely not. You're misinterpreting things. Activation does not happen when you simply run the installer, although later. This means that what he says - there is another 'install' pending / assets on your system, which means somewhere, there is a process (invisible) always blocking things. Whatever it is, since you have not provided any real technical info, we can not advise specifically. If you are using Windows, you can check your task manager and to terminate any process setup.exe and msiexec.exe more potentially will need to manually fix / remove some registry keys. What beyond this, you will be much more accurate.

  • Installation of Iolo System Mechanic error message: cannot install because there is a conflic by Microsoft Security Essentials.

    Microsoft Security Essentials has been uninstalled and I can not find remnants of anywhere I can think of research. Something is always running in the background or otherwise to prevent this installation. I recently had other problems installation, update to install 4.5 etc.; but, despite this, I had to go into services and manually start the Microsoft Live just before you install something. I'm puzzled as to what part of the software MS Essentials is hiding somewhere. It works almost like a virus...

    Have you tried installs with a beginning of 'Clean' of XP using msconfig etc.

    Any help appreciated

    Hi acls9862083,

  • Windows 7 complete edition; Windows Update does not work, cannot install SP1 failed to install Security Essentials, ect...

    I have a laptop Alienware M17x R2 that was running Windows 7 Ultimate SP1. Recently, the hard drive crashed. I replaced the hard drive and reinstalled the operating system using my recovery disks.
    Loading Windows 7 Ultimate without SP1 recovery disks. I find that I can not get Windows Update in order to run - it says that "Windows Update cannot currently check for updates, because the service is not running." You may have to restart your computer. »
    I rebooted the computer several times, without success. When I go into Services, the Windows Update Service is running and the value "automatic (delayed start). Remote procedure call is also started. The Background Intelligent Transfer Service is currently not started and is set to "Manual".

    I ran Fixit of Windows Update and Windows Update diagnosis, without result. The diagnosis of WU came up with two questions: "registration for the Service is missing or corrupt - fixed" and "the recent updates - fixed installation problems.

    I also downloaded the SP1 from the Microsoft Download site and tried to install it. Installation failed with error code "E_UNEXPECTED (0x8000ffff).

    I tried to run the system update readiness tool, but it has also failed with an error "0xc8000247."

    I also tried to download and install Microsoft Security Essentials. Which is also impossible to install with an error code '0x8004FF91 '.

    I did a clean boot, but SP1 still wouldn't install and Windows Update still does not work.

    Then I made a new reinstall of the operating system of the drive Alienware Windows 7 Ultimate original, with essentially the same result. I couldn't update anything. I'm kind of pulling my hair at this point... the machine has worked until the hard drive crashed.

    Anyone has any ideas on where to go from here?

  • Windows 7 - error Code: 80070643 (cannot install the Office updates)

    Update KB982158 error 80070643___
    Hi - I'm under Win7 pro with Office 2010 - new brand Toshiba, so not old stuff to get in the way. I tried everything to get the Power Point KB982158 update to load, but get the error code 80070643. Well, I hope that I have tried everything!

    What does work is: try to install manually. unloading and reloading PPt and try to update; tried the 'Fix - it' KB suggested for a similar problem (error different message -0 x 80070646); tried to check the registry keys according to http://social.answers.microsoft.com/Forums/en-US/vistawu/thread/18449f60-c149-4eaf-b8e6-a2880cd7232b - the first two hits are as they are supposed to be, but under local_machine etc. There is no AppData, there is a CommonAppData whose value is % ProgramData

    should I change the value of %userprofile%\AppData\Roaming?

    or I'm far from base, is there another solution? afraid to touch anything without the advice of expert-thank you

    Hello

    You upgrade to Office 2010 or did you do a fresh install?

    KB982158 is an update of security for Microsoft Office PowerPoint 2007. As you have already installed Office 2010, you don't need this update.
    I suggest you remove all components of Office 2007 from the computer, including add-ins for Office 2007 from the control panel
    and see if that fixes the problem.

    Follow these steps:
    1. Click Start, then Control Panel.
    2. click on programs or features.
    From here you can remove office 2007 and its components.

    Refer to this link for help:
    http://Windows.Microsoft.com/en-us/Windows7/uninstall-or-change-a-program

    I also want to mention that if you get the same error code when installing other updates, you can then follow the steps in the items listed
    in my previous post. You can perform the steps of Vista on the computer Windows 7 from the first link. Also since the second link may be made
    on a Windows 7 computer.

    You can also post the question in the Forums of Microsoft Office for assistance.
