I have just bought a new computer with Vista 64 bit operating system. My old machine ran windows xp. I have tried to load norton 2007 onto my new computer but a dialogue box appears telling me that it is only for use with XP. It refers me back to Symantec for their update patch. However after downloading it when I try to install it it says I need to install norton 2007 first. I can't install either of them without the other being installed first. Does anyone know how to resolve this issue. Any help would be appreciated Anne.
