Driver for Ghost Custom Recovery Disk

Ghost 15 says that I need the AMD AHCI Compatible RAID controller driver on my custom recovery disk. It says that it has to be 32 bit. I can only find the executable file (Installshield Wizard) to download the driver but it will not download the driver because I am running Windows 7 64-bit. Any ideas?
