Mathcad Prime 11 Student Edition - Issue Finding Product Code

Hi everyone. I purchased a 1-year student license for Mathcad Prime Version 11. I am having some issues launching the software and need to use my Product Code. However, I do not know where to find it.

If someone could tell me where I can find the Product code for the edition of Mathcad that I have purchased, that would be much appreciated. When I purchased the license for Mathcad Prime 11, I received 3 confirmation emails, one of them having a Product Key, which began with MT. However, I was made aware that this is not, in fact, the actual Product Code. Please tell me where it is located. Thank you for your help.
