A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connection.(Provider: SQL Network Interfaces, Error:52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly installed and that the Local Database Runtime feature is enabled.)

I created an app which uses the SQL Server Database tables. When I run it on an external PC without any SQL Server Express tools, I am getting the above error. How can I make every PC install SQL Server Express tools?

    If your app utilize a SQL Server database, then it is mandatory to have a running SQL Server instance.

    How can I make every PC install SQL Server Express tools?

    Not "tools" = SSMS, the database engine is required. If no installation exists, then download the free Express Edition and install it on the client machine.

    Welcome to Microsoft Q&A!

    Provider: SQL Network Interfaces, Error:52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly installed and that the Local Database Runtime feature is enabled.

    You need check if LocalDB feature is installed.
