Models missing from PSPICE - OrCAD 16.2

Hello

I have a problem. I can't simulate a very simple circuit because the models are missing. I am very new to OrCAD (version 16.2) so I was doing the tutorial on creating a schematic of full adder and simulating it as per the OrCAD's tutorial. As per the instructions I should be able to simulate but I can't because of the problem I earlier stated.

 In the Simulation Setting -> Configuration Files -> Library the library path field has the following in it "C:\OrCAD\OrCAD_16.2\tools\PSpice\UserLib";"C:\OrCAD\OrCAD_16.2\tools\PSpice\Library"

I suspect more information needs to be filled but I am surprised that the tutorial example didn't address it. I get the feeling that some .MODEL command is missing from the netlist. Please let me know exactly how to resolve it. Here are the netlist (based on the tutorial) & the errors. Thank you very much
