Invitation code: my problem

“You will need this code to activate your free license and access membership benefits.”
Where exactly do i have to enter the given code and what are benefits. Any information regarding this will be a help as just got the downloadable link and i have downloaded but i’m completely lost about this code they have given.
Lastly how to i check whether my license is activated or not?

You need to give the code in ratio blloc services app or bllocdesk as per your mode for installation of ratio.
From this release onwards there no pro or light version.
