Reply to Kontrol Z2 mixer

So i bought a Kontrol Z2 and im using a laptop that my dad gave me it has good specs just one problem. It does not have windows 7 and the software that comes with the Kontrol Z2 does not allow you to use it unless you have windows 7. I am looking for a program that I can use it with. Currently the programs i have are DJ Intro by serato(came with a control i got for christmas[numark mixtrack pro]) and I have a program suggested by a friend called virtual DJ home free(If i can use the mixer with this program please let me know how.)

I would appreciate it that when you suggest a program tell me if there is a specific way i need to "sync" the program and mixer, and if not tell me if i can just plug it in and go!
Thanks for all the help!
