Install Microsoft SQL Server and verify that you can connect to the default instance of Microsoft SQL Server using Windows Authentication. 

Note: Setup connects to the Microsoft SQL Server instance to obtain the SQL version number. If Setup is unable to connect, this prerequisite will fail. This failure typically occurs because the Windows service for the Microsoft SQL Server instance is not running, or because the user running Setup does not have permission to query the database.
