The License Activator node enables all matchmaker toolbox nodes by validating the signed license file you received from exorbyte.
This node requires no manual configuration. Upon execution, it automatically retrieves and validates the license:

• On local KNIME installations, it reads the license from a predefined location in your workspace.
• On KNIME Hub, the license must be provided via a HubAuthenticator and SecretRetriever node setup. In this case, the license path should be passed as a flow variable named: exorbyte.license_path

To obtain and place the license file, you must first use the License Requester node. This node initiates the license request process and stores the license file in the appropriate location.
If the license is valid, matchmaker toolbox nodes are activated for your session.
Important: This node must be executed before any matchmaker toolbox nodes (except the License Requester node) in your workflow. To ensure this, connect the License Activator node to downstream nodes using flow variable connections. This guarantees that the license is validated before any licensed features are used.
Once activation is successful, the node defines the following flow variables:

• exorbyte.license_activated = true
• exorbyte.license_file = <path to license file>

In case of a license provided by a SecretRetriever exorbyte.license_file may refer to a temporary location.
You can use these variables to trigger conditional workflow logic or display license status downstream.
