Estoy intentando instalar las herramientas de datos de SQL Server - Visual Studio 2015, pero sigo recibiendo un "error no especificado".

El archivo de registro está enhttps://drive.google.com/open?id=0B3CEKzS2Sw8OODNJOXZJVGRWQlU.

Ya tengo instalado Visual Studio Professional 2015.

Quiero instalar SSDT 2015 porque mis bases de datos se migraron recientemente de SQL Server 2008 R2 a 2014, y necesito usar SSIS. Anteriormente, utilicé SQL Server Business Intelligence Development Studio para crear mis paquetes DTS, que todavía tengo instalados para acceder a paquetes antiguos.

Intenté encontrar una solución a mi problema, pero todo parece ser sobre problemas de instalación de VS 2013.

Avíseme si necesito proporcionar más información.

Aquí está la sección relevante del archivo de registro vinculado.
