linking libeng.lib problem in VC++ 2010

I am trying to write a C++ program using MS VC++ 2010 on Windows 7 64-bit. I have a Matlab 2011 and configured all. Set Include and lib path in Windows environment variable, run matlab as a com server, include all library and include info in vc++ project settings but still the linker say:

Warning  1  warning LNK4248: unresolved typeref token (0100000B) for 'engine'; image may not run  C:\Users\Administrator\Documents\Visual Studio 2010\Projects\TestMatlabAppWin64\TestMatlabAppWin64\TestMatlabAppWin64.obj  TestMatlabAppWin64

Error  2  error LNK2028: unresolved token (0A000008) "extern "C" struct engine * __cdecl engOpen(char const *)" (?engOpen@@$$J0YAPAUengine@@PBD@Z) referenced in function "int __clrcall main(cli::array<class System::String ^ >^)" (?main@@$$HYMHP$01AP$AAVString@System@@@Z)  C:\Users\Administrator\Documents\Visual Studio 2010\Projects\TestMatlabAppWin64\TestMatlabAppWin64\TestMatlabAppWin64.obj  TestMatlabAppWin64

The program I wrote is:

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello World");
  Engine* ep=0;
  ep=engOpen(NULL);
  engClose(ep);
    return 0;
}

and the stdafx.h contains:

#pragma once
#pragma comment(lib, "libeng.lib")

// TODO: reference additional headers your program requires here
#include<engine.h>

Have you configured your Linker properties to the path where libeng.lib is present and also included libeng.lib in the Additional Dependencies? If you still see the same error, make sure that your VC++ project is configured to compile for a 64-bit target (by default, it compiles a 32-bit binary which cannot link against a 64-bit libeng.lib).
