Although there is no official information about this add-in, I can assure you that the package has been installed on Windows 7 x64 using Microsoft Office 2010. Office 2010 is pretty much the same as 2013 regarding the way it operates and once instaled, the add-in is found on Add-ins ribbon. Just give it a try and you will see it works, but you will need to open a compatible Pivot document.
