If you expand the zip file that the product came in,  what folders do have? 

As others have said sometimes manual moving these folders to one of your existing "Content" folders allows DazStudio to find them.

But remember DazStudio is flexible and will search for your files in whatever folder you point to in the preferences/content tab.  You can literally have dozens of content library folders and dazstudio will find them all, and on various drives as long as you point to them properly in preferences.
