Do you need to buy a copy of Norton 15.0 for each Windows 7 PC

Hi,

 

   Previously I ran Norton Ghost 14.0 with XP.  I used one copy of ghost for 2 XP PCs.

 

   I now have a Windows 7 PC with Norton Ghost 15.0.  

 

   I am planning on replacing  my son's XP PC with Windows 7.

 

   Do I need to buy another copy of Ghost 15.0?  I see the box says for 1 PC use.
