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. Some reports in the dashboard use ADOMD.NET to access internal data that provides reporting data on PowerPivot query processing and server health in the farm.
