Error Monitor is not license or not installed

Try the following:

1. First, verify that the license currently installed includes the monitor you are trying to add.
2. If the monitor does appear in the license information, then
a. Close the Controller.
b. Go to \bin directory, and double click on the following files
• register_controller.bat
• set_mon.bat
This will reregister all the DLLs associate with the controller and monitors.
3. Restart the Controller and try to add the monitor again.
