Creating a Wolfram Account
Go to user.wolfram.com and click “Create Account.”
Fill out the information requested and click “Create Wolfram ID”
You’ll then receive an e-mail from Wolfram asking you to verify your e-mail address. Click on the link in the e-mail, and your account will be automatically verified. Once you’ve done that, proceed to the directions for your specific type of installation.
Fill out the form with the relevant information. You will then be given an activation key in the format XXXX-XXXX-XXXXXX. You will also be e-mailed a copy of the key. Create a software install request at help.cnu.edu to have the software installed on your machine.
The first time you run Mathematica, you’ll be prompted for your activation key. Enter the key that you got during the key request process and press Activate. You’ll need to be connected to the Internet to activate your software.
Accept the license agreement on the next page. You’ll then be able to use Mathematica.
