Hi Roshan,
The licensing goes entirely through Mendix Support. What I would do if I were you is contact them. Then you will get the correct answer in a relatively fast way.
Here are the contact details: https://support.mendix.com/hc/en-us
By the way, you do not need a license for the development environment. You are free to develop the application on your laptop with a dev environment that is on your laptop (by default with Mendix). You only need a license from Mendix if you want to deploy your application to Test, Acceptance or Production.
