ms security essentials - How do I install Windows Defender/MSE on Server 2012?

On earlier versions of Windows client and server you could install Microsoft Security Essentials, free antivirus from Microsoft. In Windows 8 client, it is integrated into Windows Defender. However, I see no such option in Windows Server 2012 and attempts to install MSE fail.

Answer

I set the compatibility mode for the installer to Windows 7 and then started it with the /disableoslimit command line parameter.
