When you try to connect Tableau Desktop to a Microsoft PowerPivot database, the following error occurs:
The drivers necessary to connect to this database server are not properly installed.  Visit to download driver setup files.
It appears that you don't have Tableau PowerPivot Add-In (Excel Add-In) installed. Please install Tableau PowerPivot Add-In and try again.
