I can't get eDrawings to open anything.

I have SW 2014 and we are trying to get viewers on all the office computers so anyone can view and print a SolidWorks drawing.  We downloaded and installed the 2014 eDrawings and are still unable to open any .SLDDRW files.  What do I need to install in order to just view and print a .SLDDRW file?  Making PDF's isn't a solution.  Thanks.
