Todo Sharepoint: Problemas con los content types de Reporting Services en Sharepoint 2013

Después de haber instalado reporting services en modo integrado como explica el siguiente procedimiento de technet: http://msdn.microsoft.com/en-us/library/jj219068.aspx, los content types de Reporting Services no me aparecían (había activado Report Server Integration Feature en el site collection)

Trate de desactivar y activar vía powershell la feature de Report Server Integration Feature, y seguía sin aparecer los content types (Enable-SPFeature -Identity E8389EC7-70FD-4179-A1C4-6FCB4342D7A0 -Url http://sharepoint/ -Force). También me lanzaba el error en algunos sitescollection:The content type with Id 0x010100C3676CDFA2F24E1D949A8BF2B06F6B8B defined in feature {e8389ec7-70fd-4179-a1c4-6fcb4342d7a0} was found in the current site collection or in a subsite.
Entonces lo que hice fue desinstalar desde “Programs and feature” el add-In de SSRS. Lo hice en cada servidor de mi granja (1 WFE y 1 App Server)

Reinicie los servidores.

Primero les detallo la topología de la granja:

1 WFE
1 Application Server
1 Database Server

A continuación extraje el archivo rsSharePoint.msi de la ISO SQL Server 2012 Service Pack 1 x64 y la copie a D:\Temp

Después ingresé via línea de comandos (recuerda ejecutarla como Run as administrator) , y ejecuté lo siguiente:

Msiexec.exe /i rsSharePoint.msi SKIPCA=1

Este paso lo hice tanto en el WFE como en el Application Server.

El siguiente paso SOLO lo hice en el servidor de Application Server.

Ingrese a %temp% del servidor, es decir al folder Temp del usuario actual: \Users\<your name>\AppData\Local\Temp

En ese directorio debería estar el .exe, rsCustomAction.exe

A continuación ejecute en el directorio de temp: .\rsCustomAction.exe /i

Después de 10 minutos, finalizó el proceso. Recuerda sólo ejecutar este comando en un servidor.
