Query: Does not work

After 2 days - 7 hours online with tech chat yesterday and 1.5 hours on the phone today, this software will not completely run on my office pc. I have followed every article, every change, every setting (some they have had me do 3 times!), still same problem, same error message. They finally refunded my money and told me to buy a disk instead of downloading. I installed Norton System Works 2007 on home PC and spent 2 days trying to get all the features working on my laptop. This is the last year I will buy Norton anything!
