When I am selecting options to install using the new installer I see that Install button remains disabled for some time leading me to believe that there are some pre-reqs that are missing in my selection.
Button eventually gets enabled but nothing in the UX that indicates it is doing some work. Adding a little messages saying "calculating" or something similar would help.
