My guess is some other process has this file locked. It works fine
for me. Try and rename the file in explorer to test it.

Also check the file system permissions (by default it should be
SYSTEM which should have enough access). Classic will read the
changes to the firebird.conf when you connect. Superserver needs the
service to be restarted.
