You may want to deactivate a license from an iLok dongle in order to use it with iLok Cloud. 

To do so, please follow the following steps:

• Open the iLok License Manager application
• Select your license inside your iLok and drag it onto your iLok username. 
• A message should pop up. Click "ok" to Confirm Deactivation.

Your license should now appear in the "Available" tab. You can now open a Cloud Session from the File menu and enjoy iLok Cloud!
