You can run HVAC-Diagram.exe in a command terminal without specifying any input file, if there is a file eplusout.bnd
in your current working directory. Therefore you have to rename your bnd-file to be processed. When HVAC-Diagram program fails you can study the error message(s) in the command terminal as well as in the erroneous svg-file if created.
I have recently posted a similar question at EnergyPlus Helpdesk website and sent an idf-file for analysis to EnergyPlus Support.

Running OpenStudio simulations, a svg-diagram usually is not created, but you can create one yourself by the described method, or by writing a script or OpenStudio measure. This can be quite useful, since OpenStudio HVAC schematics do not necessarily display all the loops of a system, e.g. when deploying (water-to-air) heat-pumps, the corresponding air-loops for heating and cooling coils cannot be seen in OpenStudio.
I have recently posted a similar question bug report at EnergyPlus Helpdesk website and sent an idf-file for analysis to EnergyPlus Support. As M.J. Witte has pointed out, the HVAC-Diagram is a bit fragile, and an issue for bug fix has been added for developers.
