What you are seeing is part of the User Account Control features of
Vista. It is not really a Firebird issue, but more a consequence of
not following Microsoft's design guidelines; in particular, programs
that can be run as non-administrators must not try to write to
C:\Program Files, C:\Windows, or HKEY_LOCAL_MACHINE. Vista's registry
and file virtualization
will redirect those attempts.
