Windows 11 Professional 64-bit, local install of Oracle 21c, no network
Trying to start Listener and I get this error:

I have set environment variables as follows:
C:\>set ORACLE_HOME=C:\app\Oracle\product\21.0.0\network\
C:\>set PATH=%PATH%;%ORACLE_HOME%\bin
When I try to start the Listener as a service I get this message:

I don't know what to try next.
