After adding the local Administrators group and rebooting the server, we were able to complete the SQL Server 2012 Express installation and continue on with the Lync Server 2013 install:

If you are installing Lync Server 2013 on an OS that has been hardened, ensure that the user doing the install has all the rights necessary for a smooth installation.
