How to solve the problem when connecting to sql server(ADO.NET)?

Question

C++ / C#

Connection string: Data Source=(localdb)\mssqllocaldb;Initial Catalog=SimpleLogin;Integrated Security=True;Pooling=False.
Everything works on my computer, but when I run it on another computer, I get the following error:
"An error occurred while establishing a connection to SQL Server, either with a network or with a specific instance. The server was not found or is not available. Make sure that the instance name is correct and that on SQL Server allowed remote connections.(provider: SQL Network Interfaces, error: 52 - Local Database Runtime component not found. Check that SQL Server Express is properly installed and use of Local Database Runtime component is enabled"
I understand that in order to solve the problem, I need to check if Microsoft sql server local db is installed on the system, and if not, install it?
