I am not able to enter a product key, either. I have MS Office 2007 Small
Business on my computer and I just downloaded OneNote a couple of weeks ago.
I want to activate OneNote, but it won't accept my full version product key
(it has a rip in it so I'm guessing at one of the digits and it could be
wrongt). When I choose the option to Activate - then Pay for a product key
online, my browser launches, but there's nothing showing on it. Another
screen opens prompting me for a product key. How do I get a product key to
activate (and pay for) my OneNote product?
