To obtain a superpotential contribution from a D3-instanton in type IIB string theory, two fermionic zero modes should be present on the worldvolume of a D3-brane wrapping a four-cycle. We discuss this criterium in the presence of fluxes for different configurations of O-planes and Euclidean D3-branes.
