Hi Leigh,

yes, we had this exact problem (with D6 tho) and we had to basically go
into the VCL and edit the code ourselves. It was suggested online by
someone (can't remember who), but we basically edited ComServ.pas,
editing the TComServer.Intialize as follows:


procedure TComServer.Initialize;
begin
  try
    UpdateRegistry(FStartMode <> smUnregServer);
  except
    on EOleSysError do
      if FStartMode = smRegServer then raise;
    on E: EOleRegistrationError do
      // User may not have write access to the registry.
      // Squelch the exception unless we were explicitly told to register.
      if FStartMode = smRegServer then raise;
  end;
  if FStartMode in [smRegServer, smUnregServer] then Halt;
  ComClassManager.ForEachFactory(Self, FactoryRegisterClassObject);
end;


Hope this helps,

Cheers,
Phil.
