Hello! Currently i have a nis with up to 3 pc's. Two nis is installed in my computer and my laptop. I have an extra avaliable. So i go to my friends house so he askes me can i install my nis on his computer. I said sure since i had one avaliable. So i install nis and enter my product key. Then it says "norton installlations exceeded" Then i remembered before my old laptop got destroyed by falling off the window (dont ask) it had norton and i never had a chance to uninstall it. So i really need to add norton to my friends account but i dont know how to cancel that one extra pc even though its broken. HELP PLEASE!!!!
