I already have Norton 360 version 5.1...(the lastest) installed on (3) of my computers. My subscription expires in about
30 days, I purchased yesterday from retail Norton 360 version 5.0, instead of installing from the cd over what I have, can I just put in the new product Key code from the new product? I always buy and new CD, because I like to have to cd in case anything
happens and I have to reinstall. But I don't want to install a older version then have to do all the updating again to get to where I am now with my version 5.1, so was curious if I could just go to my settings where it says to renew subscription and enter the new Product Key code.
