IFileSaveDialog - The RPC server is unavailable

I use interface IFileSaveDialog from MS COM C++. I used example, but with minor changes:

int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE, PWSTR pCmdLine, int nCmdShow)
{
    HRESULT hr = CoInitializeEx(NULL, COINIT_APARTMENTTHREADED |
        COINIT_DISABLE_OLE1DDE);
    if (SUCCEEDED(hr))
    {
        IFileOpenDialog* pFileOpen;
        hr = CoCreateInstance(CLSID_FileOpenDialog, NULL, CLSCTX_ALL,
            IID_IFileOpenDialog, reinterpret_cast<void**>(&pFileOpen));
        if (SUCCEEDED(hr))
        {
            hr = pFileOpen->Show(NULL);
            pFileOpen->Release();
        }
        CoUninitialize();
    }
    return 0;
}

This is working, but debugger visual studio writed list errors:
