Hi, I purchased and installed the Norton Antivirus 2010 on my computer, 1 license, and am happy with the results. I want the same software on another computer, but am wondering if I can save myself a trip to the store to pick up another CD. Can I use the same disc to install the bulk of the software, then go online and register and license the product? I only paid $20 for this at Sams Club and would like to pay the same price.
