We are close to going live and are working through various permissions. At the moment we are trying to get the option to export out of Report Archive to work and I am failing miserably. 

First the “Export” button wasn’t active (greyed out)

then I magically got that to work; however, we would get an error that indicated “The File Cannot be Created”
 

Can anyone tell me what I need to grant to make this work as designed.
