Mathematica is currently installed in many labs across campus. The site license currently provides access to Mathematica, Network Mathematica, webMathematica Amateur and Wolfram Workbench. Network licenses are available for use on UTD owned computers on the UTD network.
For non-networked (or sometimes networked - a laptop perhaps) UTD owned systems, there is a local machine license. Standalone licensed systems will need to have their license codes updated yearly. Network licensed systems do not need to worry, as IR will renew the license on the license server yearly.
There is a knowledge base available for quick reference.
If you are brand-new to Mathematica, below are some suggestions on the best ways to get started.
