Also for those updating from Norton Systemworks, don't attempt to update until you have uninstalled 2001, update XP then install 2002.
As a matter of interest walking down the Tottenham Court Road I managed to buy an upgrade of NSW2002 for £29.99 at MicroAndvika
http://www.microanvika.co.uk/ In other shops the update was not available and full product about £60.
