Installing Mathematica for the first time

1. Login to the Wolfram User Portal for Students using your UCInetID@uci.edu email address. You can create an account for free if you don't already have one.
2. Specify your Department from the pulldown menu. If yours isn't listed, choose Other and enter it in the field.
3. The Product pulldown menu will default to the only version available: Mathematica for Sites (Single Machine).
4. The Version pulldown menu will default to the current version, but you can choose to download an older supported version. 
5. Enter your Anticipated Graduation date using the pulldown menus and then select Submit.
6. Follow the steps on the next page to begin the download. The software will come with a key allowing its use for a limited period of time (15 days). Within a couple of days you'll receive an email with instructions on how to activate a key that will work through July of the following year.

Wolfram will automatically send you an email with instructions each year when it's time to renew the license.
