**EDIT**
Disregard, I just found the issue. I had not put the proper "FSX_PLN=" for "[MS-FLIGHTSIMULATOR]" it should have been the following:
FSX_PLN=\\P3D2015\C\Users\Robert\Documents\Prepar3D v3 Files
All fixed now
For some reason FSBuild reports the error again. Running P3D on a networked PC as per my OP above. I don't understand that it wants the user to point to the main sim directory, how is the FP supposed to show up in the Flight Sim X or P3D Files located in the Documents folder? What am I doing wrong?
This is what the FSBuild.cfg looks like:
