I have a problem reinstalling trend micro internet security 2006 (on windows XP home SP2). I get to the extraction of the files to install it but when I try to install it again I get this warning box (link to picture below). I assume the system detects the older installation of it. How would go about removing any occurance of the older program (registry entries/directory etc.). I looked in the add remove programs thru the control panel but it doesn't show... Any help is much appreciative, Thx.
