There will not be a 16.3 version of Schematics, the site does say that Cadence may withdraw support for this at any time and, after 10 years, suppport of Schematics has ended.

There is a tutorial on spice without schematic capture here: http://www.seas.upenn.edu/~jan/spice/spice.overview.html
To input the schematic graphically, use OrCAD Capture, this has all the facilities to run a PSpice simulation from the schematic design, start an Analog / Mixed AD project to get PSpice simulation functionality fromteh schematic. OR, use the text netlist approach and run PSpice AD on the CIR file.
PSpice Schematics v16.3 may be obtained from http://www.cadence.com/products/orcad/pages/downloads.aspx#installer
