The Paladin :
I would download a fresh copy and see, AI Suite 3 is board specific , following instructions on this page
http://www.asus.com/us/support/FAQ/1012780
I downloaded the latest version of Asus Suite 3 from the website and tried to install it but the same problem happened again the setup.exe crashed. I paid 540.00 CAD for this motherboard and the damn software doesn't work. You would think that Asus would have solved this problem after all the problems with Asus Suite 2, I guess the bottom line is all that matters these days!
