You see the generic red banner of death when attempting to install a new license file in the DLP Enforce Server.

The localhost log contains this entry when attempting to install the license file

Message: Unexpected exception while processing request:

Resolution

1. Remove the current licenses from the “ProgramData > Symantec > DataLossPrevention > EnforceServer > <version> > license” directory. (Keep the old license as a backup in case the new file does not work.)
2. Copy the new license file into the license directory.
3. Restart the Enforce Server services.
4. Confirm that the new license file has been applied.
