Install Microsoft Security Essentials Without Genuine Validation Check

March 18, 2010 | Filed under Windows

;

Microsoft Security Essentials is the free antivirus developed and provided by Microsoft for free to Windows XP, Vista and 7 users. It has been very good detection against virus and it is light which does not put a lot of load on your computer. However to install Microsoft Security Essentials, the user must go through the genuine validation check first. If the genuine validation passes, the installation continues but if failed, the user cannot proceed with the installation showing the message “This copy of Windows did not pass genuine validation. You might be a victim of software counterfeiting” and will be either asked to close the setup or get a genuine Windows.

Unable to install Microsoft Security Essentials

If you do not have Windows Genuine Advantage (WGA) installed because you want privacy and does not trust what information is being constantly sent to Microsoft, then here is a method on how to install Microsoft Security Essentials bypassing the genuine validation check.

1. Download Microsoft Security Essentials.

2. Right click on mssefullinstall-x86fre-en-us-xp.exe, go to 7-Zip and click Extract to “mssefullinstall-x86fre-en-us-xp.exe\”

extract microsoft security essentials

3. Download MSSE Genuine Check Bypass Loader, extract and copy the loader.exe file to the mssefullinstall-x86fre-en-us-xp.exe folder.

4. Run loader.exe and Microsoft Security Essentials setup will launch. Follow the on-screen instructions and when asked validate your Windows, just continue with it. Within a few seconds you will get a message “This copy of Windows passed genuine validation”.

You can now update and use Microsoft Security Essentials as normal. However you will notice that there are some red alert notifications in the program telling you that Windows did not pass genuine validation and you can run another validation check after you get genuine Windows.

microsoft security esssentials get genuine

This annoying message can be removed by following the steps below.

1. Press WIN+R, type %WINDIR%\system32\drivers\etc and click OK.
2. Open hosts file with a text editor, add the following entries to the file and save it.

127.0.1.1 spynettest.microsoft.com
127.0.1.1 spynet2.microsoft.com
127.0.1.1 mpa.one.microsoft.com

3. Press WIN+R, type "%ALLUSERSPROFILE%\Application Data\Windows Genuine Advantage\Data" (with quotes) and click OK. Delete the data.dat file in the data folder.

The method above only works on Windows XP. We have tried it on Windows 7 and got the error message “Unable to change access to memory region!” when trying to run the loader.exe. Unfortunately every running loader.exe with Windows XP SP3 compatibility mode also won’t work.

    There’s another method. Install an older version of msse from here: http://depositfiles.com/en/files/c99wndwqu and update it.

    I wish microsoft would stop with this annoying messages that only hurt legitimate customers. dumb.

    thank you for this fix.

  40. Monte says:

    Anyone made it work with XP SP3 ???
    The loader starts, then it starts MSE install, then just freezes and get stuck on validation ( – Put breakpoint on check at 018AE559h…[OK]).
    Yes, I have SP3… Is that why it does not work ?

  41. Aashit says:

  42. Neltari says:

    “It says “Creating process…[FAIL]”

    What’s wrong?
    I’m using Windows 7 Ultimate x64″

    I got that too, Windows 7 Enterprise x64 here.

  43. NoDo says:

    you can try this when cutting off your connection to the net
    https://www.microsoft.com/security/portal/Definitions/ADL.aspx
    these are the updates of MSSE for PCs without internet connection
    i think you can disable it (connection) then install these updates then reconnect again
    i think this will trick the validation
    it worked for me :D

  44. NoDo says:

    and don’t forget to disable scheduled updating from the settings
    do it manual better to keep it on :D

  45. Shoghi says:

    This doesn’t work on Windows 7. I keep getting a FAIL while “Creating process…”.

  46. usman says:

    thanks man

  47. More info says:

    This seems to only work on 32bit windows. Do you have a 64bit version of this software?

    It keeps saying creating process….[Fail]
    My best guess is that it is 32bit only.

    Any thoughts on this?

  48. Orb says:

    Does not work on Windows 7 64bit FAIL while “Creating process…”

  49. ahmad says:

    i can instal but when i download the update, it always says Microsoft security essentials wasn’t able to complate the Virus & spyware definitions Update on….
    please make sure your computer is connected to internet & try again..
    what should i do…?

  50. afzal says:

    i have installed mse using above method, it is working fine,but from past few days, it keep bugging me to upgrade(not update,i mean “upgrade”) it, it says microsoft security essential has a new version so you should upgrade, i am ignoring it, so what should i do, should i upgrade or keep ignoring it

  54. Aniket Waknis says:

  55. lee says:

    where can I find MSSE Genuine Check Bypass Loader????

  56. Stitched says:

    In order to get the latest one to work:

    Follow instructions #1-3 below the main install instructions above (clearing files, changing hosts file, etc).

    Download the MSE installer (as directed) and use 7Zip to unpack it into a folder
    Download the validator archive, unpack it, and copy the loader.exe into the MSE unpacked folder (mseinstall/x86)
    Run the loader.exe (dos window pops up, goes through its thing but doesn’t launch installer)
    Click on setup.exe (in this folder) and it goes through the install process

    This should install the program. It worked for me (Windows XP 32 SP3)

  57. Ter says:

    HELP.
    I placed the loader.exe file into unzipped folder and after running(with both:admin rights and regular rights) the CMD screen says press any key to continue,I press a key and it says ok but next string it says FAIL…could not create a process or “EXE not found in directory” .Does anyone know how to fix this?Thanks.

  58. nexus says:

    its not worked on my pc too.. :(

  59. str7der says:

    For the people that have problems, this won’t work with security essentials v2, try to find version 1…

  60. dave says:

    thanks, you rock!

  61. Puujee says:

    Wow Awesome that is worked that error is removed thanks zhacks

  62. Monte says:

    Sorry Stitched,

    still does not work for me with MSE V.2 on XP SP3.
    Neither it did with V.1…
    With V.2, MSE reports that my copy of XP did not pass genuine validation and with V.1, the loader starts MSE install, then just freezes and get stuck…

    Any suggestions ?

  64. Broken {V} Heart says:

    Heyy, Dude !

    OOOOmmmmmmmmmmmmmmmh
    Thanks.
    It works as like as I have Genuine Windows.

  65. Dagwood says:

    Works with V.1, but after install, reports that my Windows XP Pro SP3 is not valid and that MSE will be disabled after 30 days. Any fixes?

  66. Dewa says:

    its not work on Win XP Sp2

  67. ambkeys says:

    Works great on Windows XP!

  68. king8o says:

    What’re these lines for in the host file?
    127.0.1.1 spynettest.microsoft.com
    127.0.1.1 spynet2.microsoft.com
    127.0.1.1 mpa.one.microsoft.com

    My anti-spyware blocked these changes and I think it is doing the right thing.

  69. Joey P says:

    Any news on a Win7 crack? I have a genuine windows PC, but disabled all the WGA stuff ’cause Microsuck has no business putting spyware on my machine.

  70. Eihsz says:

    Yes ! Working working thanks a lot ! ;)

  73. nik says:

    thankkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkks

  74. couchPOTATO says:

    For those who get an “EXE not found in directory” message, it’s a matter of placing the “loader.exe” file in the correct folder (the folder containing “setup.exe”, not “setup.ini”).

    The new MSE installer is named “mseinstall.exe”
    Once unzipped look for the folder “x86″.
    Place the “loader.exe” file in this folder, run it, launch “setup.exe” (which is also in this folder), and you’re good to go!

  75. Eshan says:

    Fuckin awsum… but i tried it thru diffrnt way then only it worked, earler when i was tring to run the dos file, it was giving me error(exe missing blah blah blah…the step u wrote did nt help me, so i used my own step…. i first install save the host file, deleted the data file… then extracted the file, run the mse from the under the 32 bit folder… and it worked….
    neways thanx man… u rock

  76. Nasri619 says:

    someone help me please!!!i got be detected as victim microsoft when i download this software….help me please,i cant do anything now…send me a message…

  77. Mysala says:

    As stated above, you might need to get v1 from http://www.afterdawn.com/software/security/antivirus/security_essentials_xp.cfm/v1_0_2498_0#all_versions

    Extract the exe to a folder and put the loader file in it and run that.

    The loader doesn’t work with newer versions, it just hangs after a few seconds.

  78. Pradema says:

    Ur gr8. wooooooooooooooooooooooo !!!!!!!!!!! it is still working. thnk lot. Big boss. b4 i try another many tricks but not success. thnks again.

  90. Steve says:

    Hey this worked great the first time I used it !

    However, I did a complete reinstall of Win XP – same everything, same PC, same XP copy, etc. It failed the second time. It gave a “could not find exe file” error. I noticed Microsoft changed the name of the download from “mssefullinstall-x86fre-en-us-xp.exe” to “mseinstall”.

  99. Folken says:

    In Windows 7 when run “MSSE Genuine Check Bypass Loader” with admin priv’s of course, and you see the “Unable to change access to memory region!” message, close the window and then run the RemoveWAT app (the link is above in the comments).

    Reboot, run the “Loader”, the message error will appear us again, don’t care, run the setup.exe of MSE and now we will install normally, reboot again and the soft works with the update of virus and spyware definitions.

    Sorry my bad english. :)

  100. Vishva says:

    u can get older versions from “filehippo.com”.

  101. xui says:

    Xuinya!! Poshol ty na xui!

    DISCONNECT FROM THE INTERWEBS! I use a reg edit file (add licence to your windows) then double click the original downloaded file.

  103. great thanks :) says:

    Awesome! worked like a charm, to those of you who it didn’t work for do what Stitched says: (and make sure you follow the entirety of the steps even after the validation says it hasnt passed!!! “In order to get the latest one to work:

    Follow instructions #1-3 below the main install instructions above (clearing files, changing hosts file, etc).

    Download the MSE installer (as directed) and use 7Zip to unpack it into a folder

  113. bapi mishra says:
