Hi, harlixdash
Thanks for contacting us and We are really sorry for late response.
We bought Visual Composer plugin and got its extended license. So, we have attached Visual Composer plugin in the full package of Rubino so you can install without using Visual Composer's lisence key. You should update Visual Composer from the latest version together with our Rubino theme. It is because that you do not have lisence key to update automatically. You need to update it manually. In addition, we are not the author of Visual Composer, so we have no right to give you lisence key.
If you want to have own lisence key from Visual Composer, you need to buy Visual Composer from its author directly so you are allowed to update automatically.
Best Regards,
