Web-activated network licenses use NetKey.exe to activate, deactivate, reactivate, and renew the licenses on the license server. NetKey.exe is installed during the installation of the Sentinel RMS License Manager and Sentinel RMS Utilities.
NetKey.exe can be found in the Sentinel RMS Utilities (v9.2, 8.6 & 8.5) installation folder and a shortcut is provided on the Windows Start menu. An activation key is required to activate a license. Users should always deactivate their licenses before uninstalling the License Manager and/or Sentinel RMS Utilities.
