We have been using IBOAdmin components without
any problems, to Backup/Restore our databases.

After reading Helens Firebird Book I realised we
need to be using Classic. But After Installing
Firebird Classic all of a sudden then components don't
seem to work anymore?

The line that is failing is this:

function TIBOCustomService.ParseInteger(var RunLen: Integer): Integer;
begin
result := isc_vax_integer(OutputBuffer + RunLen, 4);
RunLen := RunLen + 4;
end;

Robert.
