Is this a student license or a commercial license?
If commercial, are you on subscription?
How many times has the 2014 license been activated?
A commercial licence will let you install 2015 on the laptop under the Home Use section of the EULA. If you're on subscription you can install any 3 previous versions under Home Use. However. If you upgraded the 2014 license and are not on Subscription, you can not install 2014. Just install 2015.
The important thing to remember in Home Use is that only one instance of the software can be used at a time.
