Installing program to new computer


I’m going from a computer with windows XP to a laptop with windows 8. I started out with DVDfab in ’07 with Ver. 3 and have updated/upgraded on my old computer up to DVDfab 8 Qt ver 8.2.00.
What is the best way to get this for my laptop and be able to use it?? Do I need the License name and number or ??? to use when installing on laptop?

Also will DVDfab automatically work with Win 8?

Thanks in advance
