Lo intenté con la plataforma de instalación web y manualmente, pero ambos no funcionan.

Estoy tratando de instalar primero AspNetMVC3ToolsUpdateSetup.exe pero siempre falla con un error fatal

Traté de hacer la correcciónaquí Pero no está funcionando para mí.

Llego un poco más lejos de lo que se ve en la captura de pantalla anterior, ya que parece golpear lo que creo que es nuget y luego retroceder al instante. Sucede tan rápido que no puedo ver bien.

Tengo Visual Studios 2010 SP1 instalado.
