Solidworks Premium 2015 x64

Service Pack 1.1

I clicked on the Simulation box in the Add-in dialog, reboot SolidWorks, tried to do the Simulation tutorial for thermal analysis, all the "Study" options, except Static, are grayed out.

Is there some additional add-on I have to buy to do any of the other analysis in the list (Thermal, Frequency, Buckling, etc.) ????
