We finish the computation of the automorphisms of rationalized E_n-operads when n is at least 3, by verifying that the conditions of the Goldman-Millson theorem are satisfied for the map from the (dual) graph complex to the deformation complex of maps from the graphs cooperad to the cooperadic W-construction of the Poisson cooperad.
