How do I add a different product key to an existing installation?
I ended up buying see boxed version of Nis 2012 instead of extending my existing installation because it's cheaper. I know there's a way to add a different product key to an existing installation but I can't find how to do it. Does anyone else know how to do it? I have the subscription information for the new package in my Norton account after doing the first installation on a new PC.
