I had Norton Antivirus installed on my computer. Instead of renewing online, I decided to purchase the disc for 2010 (I've had problems renewing online in the past.) I put the disc in my computer and nothing happens. It's like my computer is not reading the disc at all. It reads other discs right away so I don't think it's an issue with my computer. I tried going to "run" to select it manually, but it does not appear - like I said, my computer is not reading the disc at all. I have Windows 2007...Help! :(
