Solution for SQL Server Express CREATE DATABASE permission denied in database 'master'

I got an exception when trying to connect to my local SQL Server Express Instance from a third party application, the exception and solution as follows.

Exception

Create failed for Database 'NavDB'. (Microsoft.SqlServer.Smo) An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) CREATE DATABASE permission denied in database 'master'. (Microsoft SQL Server, Error: 262)

Solution:

To fix this just follow the steps below:

2. Add New Administrator
3. Select 'Member of SQL Server SysAdmin role on SQLEXPRESS' and add it to right box.
4. Click Ok.
