Out of curiosity, did you install the Quartus II Web Edition Software or the Quartus II Subscription Edition Software?

Thanks for the reply.
The only version that is downloadable and usable for free, so far as I know, is the Web Edition. That's the version I installed.
Should I have installed the subscription edition and used an Academic license with it, instead? The tutorial I'm following -- tt_nios2_hardware_tutorial.pdf -- just says, "Altera Quartus II software version 11.0 or later".
An email response from Altera University Program stated; "For use with Altera's Cyclone-series low-cost families, we provide the Quartus II Web Edition software which does not require a license."
That's what I have. It doesn't allow me to use any IP. *shrug* This is making no sense.
