I just installed NIS 2009 on a new home computer, running Vista 64 bit Home Premium. Product registered fine and live update seems to be working, however the program will not update from version 16.0.0.125. Live update and pulse updates, no problems. I previously had NIS 2009 on an XP computer and it updated after install and running live update with no issues. Any help would be greatly appreciated. Thanks in advance.
