What can i do to import from inventor or solid work?

If one installed CAD import module, does it mean that one as installed inventor import module, even when it it checked during installation. If yes, why is it not initializing with my inventor 2010, even after running the registerinventorIface.bat in the CAD directory of the comsol 3.5. Please what can i do to make it possible to import from Inventor or Solidworks into Comsol Multiphysics 3.5.

Thanks
