hi. an I know someone that has an acer which isn't working right and so we are thinking of doing a restore using acer erecovery. however, he has just put norton 360 on his laptop. he bought it as a 3 coputer pack and has used it on 3 now so he does not have any more licenses available. is there a way to get this license back if i restore windows? or will he have to go and buy a new norton pack? thanks.
