I didn't have the option for 30 days like I did with 7, I had to install the key in order to continue the installation...
You have to add a file to the iso to give you access to the skip button based on what I have found. Unfortunately, I'm pretty sure between having Windows 7 Ultimate and a Window 8.1 core key and the possibility that upgrading a windows installation that has not yet been activated is impossible even with a full key, I think a clean install is in my near future. Probably better off anyway, I guess.
