SQL - Msg 39011 SQL Server was unable to communicate with the LaunchPad service

I’m very passionate to learn new technologies especially in SQL Server. To understand the functionality R Services within SQL Server 2016, I was running some R scripting code in SQL Server 2016. After writing some R scripting in SQL, I got the error as “Msg 39011 SQL Server was unable to communicate with the LaunchPad service” at runtime as given below:

It was the stuck point for me and after doing the R&D, I got the solution which stated that your “SQL Server LaunchPad (MSSQLSERVER)” services is stopped means it should be in the running mode to play with R scripting code in SQL Server 2016.

I did right click on that service and select start. 

After clicking on the start, service has been started as given below:

After starting the “SQL Server LaunchPad (MSSQLSERVER)” services, I have run my R scripting code in SQL Server 2016 again and it’s running successfully as given below:

There are two way to run that services as given below-
