If you use Power Pivot and Power Query, it is necessary to download and install these plug-ins as a standard .EXE application in Microsoft Excel 2010. I focus on direct download links and short steps how to do.
Power Pivot

Power Pivot should automatically appear as a tab if you run Excel again. If not, then you need to install Visual Studio 2010 Tools for Office Runtime:

and then go to File> Options> Add-ins and right-click COM Add-ins and choose Go ... and then check PowerPivot for Excel, picture:
Power Query
The next installation refers to Power Query, which requires a minimum of Service Pack 1 (a 64-bit version) or Service Pack 2 (a reference to a 64-bit version) for Microsoft Excel 2010.
Power Query can then be downloaded from this link:
