Problema con instalación de MotionBuilder 2012 de Autodesk

Resulta que estaba instalando el Motion Builder desde la página de Autodesk, la versión de prueba, quería ver cómo era la fluidez a la hora de hacer animaciones, como tiene kinematicas inversas y buenas herramientas que me habían comentado, nada quería comprobar por mí mismo este programa, en fin, a la hora de instalarlo, cuando está en proceso de instalación, se cierra todo, y me dice que hubo un error en la instalación, seguido de estos detalles que me deja ver:

No sé que es lo que estoy haciendo mal, o si es que, acaso mi PC no comple con los requisitos, pero pensé que si corría el 3dsMax 2012 también correria el motion builder2012, en fin, gracias desde ya a todos, bajare de todas formas, el launcher nuevamente para ver si me bajo con errores.
