no lo puedo instalar

Gente, es desesperante... no puedo instalar la demo... actualicé Java, hice las 1001, bajé programas (un java que viene con el netbeam) y nada... me sale este error... la máquina dice que el asistente para la instalación se prepara y después ese cuadrito desaparece por los siglos de los siglos... qué hago???
