Norton Error: 8504, 101

Hi I have been trying to start norton on my computer, it is a Dell XPS 410 with an intel core 2 duo and windows xp service pack 3. Every time I attempt to start Norton I get the "Error: 8504, 101 " when I try to run Norton Internet Security a program comes up "Norton AutoFix", it completes whatever it is doing and then it tells me to restart so I do so and when I atempt to open it again the same thing happens. I have tried runing the Norton Power Eraser and that did not help other, it found some things (my visual basic programs, which are not malicous, and I know they are.... I coded them). How do I fix this problem ive had Norton on this computer ever since I got it 5 years ago, and have not had this problem. Please help
