Scheduler plan not works fine (finish with errors)

Hi everybody:

Firstly, thanks in advance for your help.

I have in my corporation one Windows Server 2012 R2, with SQL Server 12.0.4436 and with .NET Framework 4.6 installed. This machine is a domain member.

I'm trying to make a scheduler plan to refresh data on my reports of PowerBI ReportServer.I have used some accounts (regular user and administrator). In all cases, I got the next error:

=======================
2018-08-29 15:06:44.9420|ERROR|4|Error Processing Data Model Refresh: SessionId: d4570878-cd8c-44d7-af89-ae6a21d9f929, Status: Error Failed to refresh the model, Exception Microsoft.AnalysisServices.OperationException: Failed to save modifications to the server. Error returned: 'The managed provider 'Microsoft.Data.Mashup' could not be instantiated. La sección 'DbProviderFactories' sólo puede aparecer una vez en cada archivo de configuración.
A connection could not be made to the data source with the Name of '63a497e0-fc84-4401-af91-f3a00fca9017'.
The managed provider 'Microsoft.Data.Mashup' could not be instantiated. No se encuentra el proveedor de datos .NET Framework solicitado. Puede que no esté instalado.
=======================

I have used the same report, with PBI ReportServer installed over Windows 10 Professional, and the scheduler plan works fine.

Any idea?

Again, thanks in advance.

Regards,
Antonio.
