The Sentinel RMS SDK is the software toolkit that your vendor used to license the application you are using. The licensed application uses the RMS license to support the license agreement you have with your vendor. It can authorize, monitor, and report the application use. However, these capabilities are provided depending upon the type of application and details of your license agreement.
The application first checks with the license to verify if the use is permitted by the license agreement. If the use is authorized, the application is allowed to run. Else, either the application exits or the user is placed into a queue to wait for authorization.
Note: Permission may be denied because someone else is already using the application, or the license has expired, or no license is installed.
