Release : All Supported
The reason you are getting this error is because Jaspersoft is unable to find its license file under the user used for starting the service.
Note: if you have installed Jaspersoft with an OS user and that user has been deleted or deactivated then it's best to reinstall Jaspersoft as a cluster. Documentation at: Upgrade Jaspersoft and Migrate Advanced Reporting Content
Alternatively, you can install a new Jaspersoft Instance and point it to the old database.
