You can simply use the Import File command in your Workbench License Manager view (in your Tools menu) to copy in the licenses.lar. This adds or updates those licenses in your local license database. You can then import licenses from your local license database when either platform (or station) connected.

Or, if your Workbench PC is Internet-connected while using the platform License Manager (or a station’s equivalent PlatformServices, License Manager view) you can use the Import command and select “Import licenses from the licensing server,” which installs the updated license in the host platform, and updates your local license database at the same time.

Alternatively, you can unzip the contents of the licenses.lar under your !\licenses folder, and use the Install File command in the License Manager to install licenses.
