While running methods dependent on the IAPWS95 property package, I encountered numerical errors associated with the Helmholtz EoS thermophysical calculations. Specifically, the binaries did not recognize the data folder [local_folder]\AppData\Local\idaes\bin\helm_data and most of the calculations were skipped when called, leading to parameters such as the molecular weight taking zero values. On the flowsheet level, this presented as a ZeroDivisionError when attempting to build the parameter dens_mol_crit from dens_mass_crit / mw.
