Is XP antivirus 2009 compatible with Vista?

I got a new computer running windows Vista but I already paid for XP antivirus 2009 on my old computer.Will I be able to transfer it to my new one or is only compatible with windows XP?
Update: I have paid $50 for that program and I'm going to use it if I can.
Update 2: Can you also give me the link to re download it because they didn't send me a CD
Update 3: please help me I google it but all I can find is remove instructions not the likn to download it. help I'm losing my $50
