title: Does SQL Server Data Tools for Business Intelligence (SSDT-BI) require a license?
body: <p>I know this question has been indirectly addressed, but I recently found the downloads for the 2012 and 2013 version of the SQL Server Data Tools for Business Intelligence.  When running for the first time after install, a dialog popped up which indicated that the 30-day trial period had expired and that I had to sign in in order to continue using the application.  I have an MSDN account so I signed in.  Now when I re-start, I no longer get the dialog from before, presumably because license information was downloaded when I signed in before.  So my question is Is a license required to use SSDT-BI or not?  And if not, why was I required to sign in?</p>
