Install ADOMD.NET on Web Front-End Servers Running Central Administration
If you install PowerPivot for SharePoint into a farm that has the topology of Central Administration, without Excel Services or PowerPivot for SharePoint, download and install the Microsoft ADOMD.NET client library if you want full access to the built-in reports in the PowerPivot management dashboard.
