title: [FireDAC][Phys][FB] file is not a valid database
body: <p>I have a problem when accessing a GDB-DataBase via the FireDAC.FB-Driver.
  The strange thing here is, that if I set up the connection at designtime, everything works fine with</p>
  
  <p><code>DriverID = FB</code></p>
  
  <p><code>Server = 127.0.0.1</code></p>
  
  <p><code>Protocol = TCPIP</code></p>
  
  <p>If I try the same connection params at runtime however it gives me a <code>[FireDAC][Phys][FB] file is not a valid database</code>-Error.</p>
  
  <p>Units <code>FireDAC.Phys.FB</code> <code>FireDAC.Phys.FBDef</code> are both included. I even tried to set all possible dll-Files as <code>VendorLib</code>, but it doesn't change anything.</p>
  
  <p>I know *.GDB is usually a InterBase-DataBase, but I have a FireBird-Server running, and to my understanding access via FB-Driver should work, since it does when specifying the connection at designtime.</p>
  
  <p>Firebird-Server-Version is 2.5.3.26778 32-Bit</p>
  
  <p>DelphiVersion is XE7</p>
  
  <p><strong>Additional Edit:</strong> ODS of the DataBase-File is 11.2 (Firebird 2.5/InterBase 7.5)</p>
  
  <p>Any ideas what I'm doing wrong?</p>
