  We study the influence of dipole-dipole interaction on the formation of
vortices in a rotating dipolar Bose-Einstein condensate (BEC) of $^{52}$Cr and
$^{164}$Dy atoms in quasi two-dimensional geometry. By numerically solving the
corresponding time-dependent mean-field Gross-Pitaevskii equation, we show that
the dipolar interaction enhances the number of vortices while a repulsive
contact interaction increases the stability of the vortices. Further, an
ordered vortex lattice of relatively large number of vortices is found in a
strongly dipolar BEC.
