Setting up Oracle DB 23 ai free on Windows

I am trying to setup a local Oracle database with 23ai, but I fail at the very basics. I am trying to connect to the DB after installation, but get > ORA-12514: Cannot connect to database. Service FREE is not registered > with the listener at host localhost port 1521. When I try checking lsnrctl for the service, I get LSNRCTL> services Anmeldung bei (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=XYZ.YOURCOMPANY.com)(PORT=1521))) TNS-12546: TNS: Berechtigung verweigert TNS-12560: Fehler bei Datenbankkommunikationsprotokoll. TNS-00516: Genehmigung verweigert 64-bit Windows Error: 13: Permission denied Anmeldung bei (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))) Der Listener unterst³tzt keine Services Der Befehl wurde erfolgreich ausgef³hrt. So for some I can't even check the services due to some permission issue. I installed the DB for the local user if that changes anything. How can I get rid of this permission issue, and how can I then connect to the DB?
