Installer keeps setting up embedded database

I'm trying to set up a fresh installation of Confluence. I've downloaded the 5.6.1 artifact and start it up. After clicking the production button, I get prompted for the license. After that point I'm kicked over to the embedded database url.

I'm now installing 5.5.6 (which let's me pick the database type) and then will upgrade to 5.6.1 from there
