I've been working my way through a book of exercises in Solidworks (Solidworks 2017 Learn by Doing) and one project requires using the Toolbox. I opened up the Design Library only to find the cryptic message, "Toolbox is not installed". Where do I find it? The book says "select Toolbox and click Add in now". No such option opens up. I've poked around a bit without success. Help!!!

Thanks,
Rick
