If you don't have the STARDOG\_HOME env variable set you should run stardog-admin from the install directory and not bin. `.\bin\stardog-admin server start`. It might be fetching the license but placing it in the wrong directory because STARDOG\_HOME is not set and you're not running it from the root of the installation directory. ---
