Resulta que estaba instalando el "MotionBuilder" desde la página de autodesk, la versión de prueva, quería ver como era la fluidez a la hora de hacer animaciones, como tiene kinematicas inversas y buenas herramientas que me habían comentado, nada quería chequiar por mi mismo este programa, en fin, a la hora de instalarlo, cuando esta 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 se que es lo que estoy haciendo mal, o si es que acaso mi pc no comple con los requisitos, pero pensé que si corria el 3d max 2012 también correria el motionbuilder 2012, en fin, gracias desde ya a todos, bajare de todas formas el launcher nuevamente para ver si me bajo con errores.
