加载驱动时出现的问题

我最近在学一些关于驱动方面的知识，但有一个问题老是解决不了代码如下
这是一段加载驱动的代码，我在我的64位CPU,64位win7系统下老下运行出错，但在32位系统上或32位cpu配64位win7却能正常运行，上面出错原因是
StartService faild() 2！这好像是路径问题，但是我的路径可以很确定没有问题的，有没有高人帮我看下哪里出问题了
#include<windows.h>
#include<winsvc.h>
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<string.h>
#include<ctype.h>

LPCWSTR DRIVER_NAME={"GENERICDRV"};
LPCWSTR DRIVER_PATH={"amifldrv64.sys"};


//加载驱动的程序，但是这个程序在win7下可能需要管理员权限才能
//打开SCManager或加载驱动
BOOL LoadNTDriver(LPCWSTR lpszDriverName,LPCWSTR lpszDriverPath)
{
DWORD dwRtn;
LPWSTR szDriverImagePath[MAX_PATH];
BOOL bRet = FALSE;

NULL,

if( hServiceMgr == NULL )
{
//OpenSCManager
printf( "OpenSCManager() Faild %d ! \n", GetLastError() );
getchar();
bRet = FALSE;
goto BeforeLeave;
}
else
{

printf( "OpenSCManager() ok ! \n" );
}

else
{

printf("StartService() Faild ERROR_SERVICE_ALREADY_RUNNING ! \n");
bRet = TRUE;
goto BeforeLeave;
}
}
}
bRet = TRUE;
//DeleteFile(szDriverImagePath);

BeforeLeave:
if(hServiceDDK)
{
CloseServiceHandle(hServiceDDK);
}
if(hServiceMgr)
{
CloseServiceHandle(hServiceMgr);
}
return bRet;
}
谢谢了。
