Model Sim license error

I started a blank project in Quartus with the default settings, created a bdx file, entered a few inputs/output lines and logic gates, created a vwf file, and tried to run the functional simulation: ...

    I got simulation working. To answer my own question in the hopes it may help a fellow noob, here are the steps that I used to get simulation working. I'm not sure if step 1 is necessary because I don't know what program is actually running the simulation, but I downloaded and installed it anyway.

    1. Download/Install Questa*-Intel® FPGA Edition (includes Starter Edition)

    2. Download license file and store it somewhere on your hard drive. I put it in my Quartus folder.

    3. Read the directions on creating a new system variable for LM_LICENSE_FILE here and do that. I used the setx command:

    setx LM_LICENSE_FILE C:\intelFPGA\license.dat;%LM_LICENSE_FILE%

    just change the full name and path to your license.

    4. Go to Quartus <tools> <license setup> and click the checkbox for use LM_LICENSE_FILE. You know you have the license set up correctly if the box already contains your license file.

    That should be it to get simulations running, but if you're like me the simulation won't display any outputs, so in the Simulation Waveform Editor window select <Simulation> <Simulation Settings> and change -noptargs to -voptargs="+acc" in both tabs, simulation and timing. Now the output waveforms will be displayed.
