Lost activation code HELP

Help

Had a hard drive crash.  Had to 100% re-install my Norton Utilities 15.0. 

 

I can not find my "activation" code?   How do I get a the or a new "activation" code?? 

 

I can find the Norton cd-rom disk but not the box it came in with the code.

Thank you very much,
