Hi, I have now had NOD32 Version 2.12.2 trialling on my system for a few weeks and have used this forum to learn as much as I can about configuring the program. I have been very happy with the product and will purchase it when the trial period runs out. I am hoping that all I will need to do is change the licence information and not go through the uninstall/reinstall/reconfigure routine. Is that possible? Elray.
