Can't configure Kleopatra Directory Services

Sorry if this is obvious, but I can’t configure Kleopatra properly as it keeps telling me

“Backend error: gpgconf does not seem to know the entry for gpg/Keyserver/keyserver”

Can’t google my way out of it …

Thanks in advance - Bob

(Running Kleopatra v 2.1.0
from gpg4win v2.1.0
on Win XP machine)
