At this point it's possible the machine is still in a bad state from the VS 2010 Beta1 failed install. AFAIK, there is currently no uninstall tool available for VS 2010. But you can follow the steps outlined in that link. For every program which is listed as 3.5, remove the component also if it's labeled as 4.0.
