I have a trial version of Norton 360 installed. I just obtained an activation code for Norton 360. How do I activate the trial version so I don’t have to uninstall and then install the product again?

Open the main Norton 360 window. At the bottom of it, click Activate Now. Then enter your product key. If you have already setup Norton Account, use your credentials to log in. If you don’t have Norton Account, you can set it up now.
