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?
