Hi Harry, welcome to Stardog. It should have given you the following prompt after telling you it couldn't find a license `Would you like to download a trial license from Stardog (y/N)?` Did you not get that? I believe that the officially supported jvm versions are 8 and 11 although I don't know of any particular reason why 14 wouldn't be ok. ---

There is. These are just warnings but it should prompt you for some further information, name and email address, and download and install the license so it's a little concerning that it's working as expected. If you're having problems at this stage I would expect you to have problems elsewhere. The command to explicitly request a license is `stardog-admin license request` but I would suggest trying to run Stardog with a Java 8 or 11 JVM. I personally recommend using [sdkman](https://sdkman.io/) if it's for your local environment and not a production install. ---
