  Results of the search for $\sim (10^{16} - 10^{17.5})$ eV primary cosmic-ray
photons with the data of the Moscow State University (MSU) Extensive Air Shower
(EAS) array are reported. The full-scale reanalysis of the data with modern
simulations of the installation does not confirm previous indications of the
excess of gamma-ray candidate events. Upper limits on the corresponding
gamma-ray flux are presented. The limits are the most stringent published ones
at energies $\sim 10^{17}$ eV.
