Microsoft Security Essentials: setup.exe – Application Error

Hi guys,
I received an application error while installing Microsoft Security Essentials version 2.
It stopped installation throwing an error message. It could not read the memory.
I terminated the program and tried to install it again but no result. Have you any idea for the problem?
Please help.
