Multisim 11 Activation Code Keygen

I purchased and downloaded the student edition of circuit design suite v12. When I go to launch the program I am asked to enter the product code/key to activate the product or begin the evaluation mode. I purchased the student edition so I could do more than the evaluation. Where do I find the activation code so I can begin using this for homework assignments?
