EnFuzion license keys are stored in file /config/enflicense.txt. Verify that the file exists and that it contains your license key.

If the license key file does not exist, copy your EnFuzion license key to /config/enflicense.txt.

If the license key file exists, but the enfdispatcher process is not running, verify that there are no messages about an invalid license in the EnFuzion log file in /work/enfuzion.log.

If your license key is invalid then the log file contains messages similar to the following:
