You will have to read the built-in license agreement. If there is no button to access it, look in the installation folder of the application. You should have all the details explained there. I was a student too, and I had ANSYS(very expensive software!) on my computer, but it was used with teacher's permission and within the area of the university. Try to activate the license, and if there will be any problems, the officials will contact you. Explain the situation and ask for further information.
