LINKS - Mark II has these system requirements:
- SQL Server 2014 SP1 Express LocalDB
- Microsoft .NET Framework 4.6 (x86 and x64)
- Windows Installer 4.5
However, when the setup is launched it automatically displays the required components and offers to install them. In most of the cases you won't need to do anything, just accept the installation of the SQL Server 2014 SP1 Express LocalDB then continue using the application's default values and it will connect automatically.
Sometimes you can start the SQL Server from the Start menu by identifying the executable file. Just type SQL server and you'll get the results.
