Recently I bought this motherboard to build my new system. My hard disk drive (HDD) is set to IDE mode. I have successfully installed Microsoft Windows 7 and the drivers from the support DVD. Everything is working fine. When I was checking for a newer BIOS on ASUS Support Site, I found this Intel Rapid Storage Technology (IRST) software. I don't recall seeing this software during the support DVD installation. Therefore, I downloaded this software, and tried to install this software. During the installation, I see this error message as shown in the picture below. Is this normal?
