I currently have Norton 360 (Standard Version) 2012. I currently have 3 PC's being used by this installation of Norton 360 (Standard Version) 2012. 2 of these have it installed on PC's in different locations other than my own home. I cannot seem to remember how I did install this on their own PC's. I would like to replace this Norton 360 version and install NIS 2013 on all three PC's. Question: Will I have to do individual re-installs of NIS 2013 after Norton 360 is removed or can they be installed simultaneously? And will I have to uninstall Norton 360 (Standard Version) 2012 separately from each PC before I do this? I am open to any suggestions on this matter and I feel I am competent enough to follow any instructions given me. Thank-you in advance for your help. :) P.S.. If there is a previous posting in this forum, could you please provide me with a link to this? thank-you.
