Trying to install 7.2.1 on

Mac Mini with VMWare Fusion 7, WIndows 8.1 IIS 8, VS 2013, ASP.NET 4.5,

Installing as admin in a blank project from NuGet console.

Build Project

Started without debugging.

Put in username, email etc.

Setup database Using either SQL server or CE.

On the screen for adding a website, Whether I choose on install a website or not:

getting a "The connectionstring property has not been initialized" error.

The database seems to be populated "no way of telling if complete as I am new to this".

Connection string is in the config as expected, with correct creds.

Rerun as "start without debbuging" returns to setup screen.

Log as follows.

Really getting quite frustrated, esp since everyone else seems to get a clean install.

Any help appreciated.
