LoadLibrary is not working

I have created an *.exe and *.dll for my project. I have provided all the correct path and data. Myexe.cpp:

#include "stdafx.h"
#include <Windows.h>

int _tmain(int argc, _TCHAR* argv[])
{
    HMODULE hInstLibrary = LoadLibrary(L("..\\Debug\\LoadDLL\\LoadDLL.dll"));// I have checked with complete path as well.
    if(hInstLibrary)
    {
        printf("Hello World");
    }
    return 0;
}

MyDLL.cpp:

#include "MyDLL.h"
#include <stdio.h>

    MyDLL::MyDLL(void)
    {

}


MyDLL::~MyDLL(void)
{
}

extern "C" __declspec(dllexport) void HelloWorld()
{
    printf("Hello DLL");
}

MyDLL.h:

#pragma once
class __declspec(dllexport) MyDLL
{
public:
    MyDLL(void);
    ~MyDLL(void);
};

extern "C" __declspec(dllexport) void HelloWorld();

I have tried providing the complete path also. But it is still failing. The hInstLibrary is setting to 0x00000. I tried in Release mode too but the problem still lies there. But when I have tried with:

HMODULE hInstLibrary = LoadLibrary(_T("C:\\Windows\\System32\\aeinv.dll"));

it does load the DLL. So, please help me where is it going wrong. The DLL gets build properly, there is absolutely no error in building DLL. Then why am I facing this problem??

Is there any setting need to be done for Debug.

You need to call GetLastError to find out what went wrong.

Edit:

You got 0x7e, which means:

ERROR_MOD_NOT_FOUND

126 (0x7E)

The specified module could not be found.

Your path is wrong. You need to fix that.
