To be able to execute graphs, CloverETL Server requires a valid license. You can install and run CloverETL Server without any license, but no graph will be executed.
There are three ways of installing the license. They work on all application servers and can be used at the same time, but only the most recent valid license is used.
We recommend using the first and easiest option (for other options, see CloverETL Server Activation Alternatives):
If the CloverETL Server has been started without assigning any license, click the Activate server link on the welcome page. You will be redirected to the Add New License form where you can upload the license file using the Browse button, or simply copy the license from the file and paste it into the License key text field.

You can skip adding a license by clicking thebutton.
