"Install App" does nothing when trying to install Mavericks I'm trying to install Mavricks and it's not working.

I already did a system update.
I'm currently on lion.



Says it's paused in launchpad.
It could be that the servers are so overwhelmed with people downloading the new operating system that you have nothing wrong other than being caught in a stampede.

I would say you might try again in 30 minutes and then back off doubling the time you wait until you get a good download.
