No worries on the 2012 thing, now that we know, it'll be easy to get you some help.

You need the SQL 2012 Client Development Tools. You can get them here: SQL SERVER 2012 EXPRESS EDITION

I think you could go with SQL Server Express with Tools (with LocalDB, Includes the database engine and SQL Server Management Studio Express). If you do not want to install a local instance of the database engine you can get the client tools only by choosing SQL Server Management Studio Express (Tools only).
