"Here are the exact steps I took:
1) I went here and signed up for the offer.
2) Next, I received an e-mail instantly from Webroot with my activation code.
3) I went here to get a link to download the software by supplying my last name and e-mail with which I signed up.
4) Webroot sent me another instant e-mail with a download link for the software.
5) After downloading the software from the link, I installed it. Before the program even installed, it asked for the activation code. After I entered it, the program installed then I had to restart my computer. This software isn't activated after you run it the first time like some programs."
