Can't open PDFs generated from Solidworks

[PhotonicEmission]

I was hoping to use this a engineering drawing reader for PDFs generated in Solidworks, but when I double click on them, it opens a blank Lector window. Things not generated in Solidworks work open fine.

I can open the files by dragging and dropping into the window, or by use File> Open menu, but double clicking from Windows explorer isn't working.
