I've played around with Simulation Express and now I'd like to try out Solidworks Simulation. I'm not sure but I believe it should be included in my premium package. I see an icon for it on the Office Products tab but it is greyed out along with TolAnalyst, Solidworks Routing, Solidworks Motion, Scan To 3D, and CircuitWorks. The only features available there are PhotoView 360 and Solidworks Toolbox. Is there some way of activating these unavailable Add Ins?
