You need to activate it in your addons - look and feel - skins

Just to add, I had to do this, on one installation, but on another I had to ensure the old madnox skin was deleted, reboot, then also try to add the zip itself before it would work. It also took about half an hour from hitting zip before it installed. I watched a show using the estuary skin & half an hour or so into the pop up "do you wish to change to this skin" appeared.
