One additional note . . .
One additional point - while you need to be logged in "on campus" to install the software, you will also need a campus network connection - wired or wireless to run it. You can use the off-campus login and still run the software as long as you're physically on the campus and actually have a network connection. SPSS has to communicate directly with a license server in order to operate.
If you have any trouble installing SPSS, you can call the CNS Helpdesk or bring your computer down. It usually just a matter of changing some settings or installing one or two prerequisite updates.
