Not able to create new Firebird database

I am new to Firebird. I installed Firebird Superserver 2.5 with "Install as application" option. I also installed FlameRobin GUI front-end. When I am trying to create a new database with SYSDBA username and masterkey as password, it displ开发者_开发技巧ays following error:

I am installing on Windows 7 and want to use it on a single PC.
