:After trying Norton 360 twice, I determined it was something I would not want on any of my computers. To clarify, I understand your problem is with multiple Windows XP systems and not Windows Vista.
You will probably have to uninstall v2 and do a cleanup. Then you can reinstall the original version - hopefully.
I suggest you check your computer for the downloaded v2 setup file in case you decide to reinstall later.
