    Microsoft Security Essentials install problem

    Hi forum members, a question please. Windows secret Newsletter and Fred Langa suggest to get MSE. I am not able to install. I have uninstalled all Malware programs, they were Spybot Search and Destroy and Spyware blaster. The Error Code is 0x80070643. Lots of info on the web about this problem. I have used all the uninstall tools mentioned in the various posts. No Joy.
    The O/S is Win 7 home premium 64 bit. The MSE download was from Microsoft for Win 7 64 bit.
    Any ideas ? If it is too difficult to diagnose on the web don't worry as I have been going along for years without a virus or any Malware problem. It was so highly recommended by Fred Langa. According to the web posts I am not the only one with this concern. Regards Peter

    Hi Peter,

    Hi Rui, yes I did but it did no good. The only thing running is Zone Alarm Pro which is not a anti Malware program. I am not uninstalling Zone Alarm as it is been with my machine for over 10 years and it causes no problems up to now. Regards Peter

    Temporarily disable the Zone Alarm prior to installing MSE.

    Hi Clint, I did but it made no difference. Same error code. From what I can gather the WSE is a anti virus and mal ware program and not a firewall. So I will just forget about it. no other anti virus or spyware etc program has ever caused me so much trouble and effort. The software either runs first time or not. If not , let Microsoft work on it some more. Thank you though for the help.Regards Peter

    Peter,

    MSE is not the only good AV app out there. If the one you had before has worked for you, there is no need to change.

    Probably it makes sense to run regularly (on-demand) some other anti-malware apps, like the free Malwarebytes AntiMalware, for additional protection, but for real time protection, changing to MSE is not an absolute must.

    Regards

    I also had the same error last year and went through many, many, emails with Microsoft support but got there in the end. I'm no expert but the problem appears to be that the MSE install gets corrupted, and then can't be overwritten by a good install so it has to be cleaned out manually. Anyway, no guarantees it will work for everyone, but this was the procedure that MS eventually provided that worked, it was painful, but it was worth it in the end, MSE has worked out very well for me.

    Step 1:


    Please follow the below steps to delete the existing Microsoft Antimalware and Microsoft Security Essentials folder in the following locations:


    Location 1: Check in "C:\Program files\Microsoft Security Essentials"


    - If the "Microsoft Security Essentials" folder is found in the above location please delete it.

    On deleting the folder please go the next location.


    Note: If you receive an "Access Denied" error message while deleting the above folder please follow the below steps to provide permissions to the folder and delete it.

    Steps to provide permissions:


    1. Click on Start.

    2. Click on Run and type CMD and press Enter.

    3. Copy and paste the below command in the command prompt window and press enter.

    Cacls "C:\Program files\Microsoft Security Essentials" /t /g everyone:f

    4. Type Exit to close the command prompt window.

    5. Now try to delete the folder in location 1.



    Location 2: Check for "C:\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Antimalware"


    To access the folder, copy and paste the below location in the Run command and press Enter:

    C:\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Antimalware


    Try to delete the folder. If you are not able to delete the folder, please follow the below step:


    Steps to provide permissions:


    1. Click on Start.

    2. Click on Run and type CMD and press Enter.

    3. Copy and paste the below command in the command prompt window and press enter.

    Cacls "C:\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Antimalware" /t /g everyone:f

    4. Type Exit to close the command prompt window.

    5. Now try to delete the folder in location 2.



    Location 3: Check for "C:\Documents and Settings\All Users\Application Data\Microsoft\Microsoft Security Essentials"


    To access the folder, copy and paste the below location in the Run command and press Enter:

    C:\Documents and Settings\All Users\Application Data\Microsoft\ Microsoft Security Essentials


    Try to delete the folder. If you are not able to delete the folder, please follow the below step:


    Steps to provide permissions:

    1. Click on Start.

    2. Click on Run and type CMD and press Enter.

    3. Copy and paste the below command in the command prompt window and press enter.

    Cacls "C:\Documents and Settings\All Users\Application Data\Microsoft\ Microsoft Security Essentials" /t /g everyone:f

    4. Type Exit to close the command prompt window.

    Now try to delete the folder in location 3.

    Step 5:


    Please follow the below instructions to download the appropriate version of the Microsoft Security Essentials for your operating system:



    1. Go to the below download link:

    http://www.microsoft.com/security_essentials/?mkt=en-us

    2. Click on "Locales and Languages" Right below the Download button and you will find following three download options for different versions of operating systems

    Windows Vista/WIN7 32-bit

    Thanks Sooty2, I copied it, tweaked it and saved the text in my TOOLS folder... It is gr8 info and useful for a future bad day. P.S. On Fred Langa's suggestion, I have now been using MS Firewall and MSE ONLY for almost 4 months with NO compromises and some real nasty (Severe) stuff found and Deleted or Quarantined. And to think that I spent years putting up with commercial packages that gave me my premature grey hair! Since installing MF and MSE, I think my hair is turning brown again!!! LOL

    I had this problem with WinXP and figured it out. May work for 7.

    I found that if Ad-Aware by Lavasoft or any part of it left on the system it will cause 0x80070643 and/or 0x8004ff01 error code. Dig it out completely. Took me 5 hours to figure this out!
