Abstract: We analyze Mtheory compactified on K3xK3 with fluxes preserving half the
supersymmetry and its Ftheory limit, which is dual to an orientifold of the
type IIB string on $K3\times T^2/Z_2$. The geometry of attractive K3 surfaces
plays a significant role in the analysis. We prove that the number of choices
for the K3 surfaces is finite and we show how they can be completely
classified. We list the possibilities in one case. We then study the instanton
effects and see that they will generically fix all of the moduli. We also
discuss situations where the instanton effects might not fix all the moduli.
