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 (v9.4, 9.2, 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.

Step by step instructions to activate, deactivate or renew licenses can be found hereNetKey Guide.pdf


Web-activated licenses are locked to multiple locking criteria including Ethernet Address, CPU Info String and UUID. Any server changes affecting any of these locking criteria, including maintenance, repair or reformatting the server, will cause the license to no longer work and also prevent the license from being deactivated. Please deactivate the license(s) before making any changes to the license server.


The license activation server ports are 80 and 443. If either of these ports is blocked, they need to be opened, otherwise license activation will not be possible. Please refer to the Error 'Port 80 (or 443) is not responding' when running activation tool for web-activated licenses article for additional information.

For products released prior to 2/4/2014, ports 8080 and 8443 were used instead of ports 80 and 443. If you are using products released prior to 2/4/2014, please upgrade to the latest version of Sentinel RMS Utilities , as ports 80 and 443 are typically opened on most systems by default.
