Do I have to remove NIS 2011 Netbook before replacing with NIS 2011 Regular ? I want to use the 3rd PC of my NIS Regular subscription for my netbook, Trial version of NIS Netbook is currently installed on my netbook. I know the keys are not interchangeable between Netbook and Regular, but I am not sure if complete removal of NIS Netbook is required before install of NIS Regular. Please advise.
