Extracting the security pin from Comcast's Norton Security Suite

I'm having problems, and when I log in to my admin account I get a dialog box labeled "one click support" telling me to use "norton removal tool" and then  reinstall Norton. This happened following a system restore.

 

I can't find the paper with the cd-key or whatever they call the stupid code needed to install the software that everone calls by a different name in my shoebox with all the codes. How can I extract it fron the current, semi-working install before I reinstall it?
