Question

I am trying to execute the example at https://theroadtodelphi.wordpress.com/2011/10/15/all-about-wifi-networks-and-wifi-adapters-using-the-wmi-and-delphi/ in visual C++, wherein:
the WMI class WiFi_AdapterAssociationInfo is queried
retrieve WiFi asset information
On windows 2012 and Windows 8.1 am getting the error that unable to locate the WMI class, the code I am executing is placed below, I am getting erro code 0x80041010, please help here:
// wmiQuery.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <string>
#include <atlbase.h> // For ATL autorelease classes (CComBSTR, CComPtr)
#include <wbemidl.h> // For WMI
#pragma comment(lib, "wbemuuid.lib") // Link to WMI library. (Can do in library includes instead)
