I downloaded the Seagate Discwizard (Acronis lite version 10.0) to backup a copy of my hard drive, but I get this error. I'm on Vista Home Premium 32-bit and my main drive is a 500GB Seagate Barracuda SATA 7200.10 drive. I'm trying to copy the contents onto my external USB Western Digital Hard Drive. I see this solution somebody posted here... http://www.wilderssecurity.com/showthread.php?t=200731 ... but I'm using a dedicated sound card (Xi-Fi XtremeGamer Fatality Pro edition) and I have my onboard sound disabled in the motherboard BIOS. I was considering buying the full version, but I can't be sure the full version will work with my system if the lite version is not compatible with my system.
