Reference design of Cyclone V Board

I've tried download in the Available Documentation (Cyclone V GX FPGA Development Kit) , kit installation which include Full installation of all files , i'm planing design a board using a FPGA cyclone V, the link to download don't work ( it download a file .exe and then i execute it , it shows me "it's not a valid win32 application"), pls who have reference designs of Cyclone V, can send me to arlen.alem (gmail)
if the staff of Altera can fix it, it would be better.
