I followed the instructions in https://support.office.com/en-US/article/Turn-on-Power-View-in-Excel-2016-for-Windows-f8fc21a6-08fc-407a-8a91-643fa848729a to turn on PowerView.
However, when I get to the step where it says to "Turn On the PowerView Add-In", nothing occurs. Clicking the button doesn't do anything.
