If you have already installed Microsoft Security Essentials final on one of your Windows machines that has no internet connection and looking for a way to update the virus definition updates, here is a quick and easy solution.

Although Microsoft clearly states on the Microsoft Security Essentials system requirements page that an Internet connection is required for installation and to download the latest virus and spyware definitions, you can still update the MSE offline. Of course, you need a computer with Internet connection to download the offline updates!

 

Once you install MSE on a machine, it will try to update the virus and spyware definition. If the machine is not connected to the Internet, it will display “Microsoft Security Essentials wasn’t able to complete the virus and spyware definition updates. Make sure your computer is connected to the Internet and try again” error.

How to update Microsoft Security Essentials Offline:

1. First you must know whether Windows XP, Windows Vista, or Windows 7 is running in a 32-bit or a 64-bit operating environment. You can find it easily by opening system properties (use Windows + Pause/Break key to open system properties).

system properties

2. Next, download the offline definition updates for MSE from Microsoft:

Download for 32-bit

Download for 64-bit

 

Just save the file on a USB stick so that you can connect the USB stick to the offline machine and then update MSE.

 

3. If you are on Windows 7/Vista, right-click on the downloaded file and select Run as administrator. If you are prompted for an administrator password or for confirmation, type the password or click Continue. And if you are on XP, simply, double-click on the file and click Ok.

    Thank you so much for this!

    Do you know if Microsoft provides those offline updates daily?

    I’ve been itching to test this out on my XP Desktop, which is my only Windows machine

    You can’t install MSE without internet connection.. (remember it has to validate the windows!) and if you want to re-install the MSE then it is better to use the offline updates… ( and the pack contains most updates*)
    there is no problem if you downloaded them daily.. but it looks like waste of time..
    *pack contains the past updates also.. when you live update them they will download a CURRENT updates..

    any dobt mail me.. help@goodkeys.co.cc
