From Denodo 7.0 onwards, the Virtual DataPort Server is usually obtaining the license from the License Manager component of the Solution Manager. In order to be able to do this, the infrastructure such as the Environments, Clusters and Servers need to be defined in the Solution Manager.
Since it seems that you are a new user to the Denodo Platform and the Solution Manager, I would recommend you to have a look at the Knowledge Base article [Ready to work with Denodo 7.0](https://community.denodo.com/kb/view/document/Ready%20to%20work%20with%20Denodo%207.0?category=Best+Practices) which explains the "Installation Key steps". It shows you every necessary step to follow in order to start working with the Denodo Platform.
As an additional information, if you are a customer with a valid Support user and you need any further help, you could also open a Support Case in the Denodo Support Site.
Hope this helps!
