이렇게 2가지가 나오는데요

어떤분이 만드신 MFC 프로그램에 Dll 위에 컴포넌트 텝에 등록해서요..
하는데요..
이런 에러가..ㅡㅡ

HRESULT            hr;
    BSTR bstrClientID = OLESTR("8882432");
    BSTR bstrClientTag = OLESTR("70E27967B73FB6F309F16CBA24E1EC07");
    BSTR bstrClientVersion = OLESTR("2");
    BSTR bstrReg = OLESTR("regstring");
    if ( IControl )
        return ;
    // Create an instance of CDDBControl using the COM interface
    hr = CoCreateInstance(CLSID_CDDBControl, NULL, CLSCTX_ALL, IID_ICDDBControl, (void **)&IControl);
    if (!SUCCEEDED(hr))
        return ;
    // The first call should set the client information within the control
    IControl->SetClientInfo(bstrClientID, bstrClientTag, bstrClientVersion, bstrReg);
    // If the user is not already registered, bring up the default registration dialog.
    if (!IControl->IsRegistered(FALSE))
        IControl->IsRegistered(TRUE);

제가 이렇게 했어요..
왜 그런지 말씀해주세요..??
