I have installed the windows XP Home Edition Service Pack 2 and I have successfully recovering mine system through BSOD with producer recovery disk. Now I have small issue on mine Microsoft Security Essentials. I am not able to install the Microsoft Security Essentials on mine system. While installing the Microsoft Security Essentials I have got the following error saying that: "The Security Essentials Installation Wizard is lost a filter manager rollup package required to entire the installation. To carry on installing Security Essentials, you have to download the necessary package." And after that I have click the "Download required package" and after that it download anything and after that it gives the error code. Now I donít know how to solve this issue. Can anyone suggest on this.
