Получение температуры процессора C++ WMI Qt

На строке hr = pEnum->Next(WBEM_INFINITE, 1, &pObject, &returned); выкидывает ошибку IDispatch error #3587, почему это происходит и как это можно исправить?

Вызов функции: LONG temp; test(&temp); qDebug() << (static_cast<double>(temp) / 10 - 273.15); Выводит 273.25, всегда.

Вот вся функция для получения температуры процессора:

    HRESULT test(LPLONG pTemperature)
{
    if (pTemperature == NULL)
           return E_INVALIDARG;
       *pTemperature = -1;
       HRESULT ci = CoInitialize(NULL); // needs comdef.h
       HRESULT hr = CoInitializeSecurity(NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_DEFAULT, RPC_C_IMP_LEVEL_IMPERSONATE, NULL, EOAC_NONE, NULL);
       qDebug() << hr;
       if ((SUCCEEDED(hr)) || hr == -2147417831)
       {
           IWbemLocator *pLocator; // needs Wbemidl.h & Wbemuuid.lib
           hr = CoCreateInstance(CLSID_WbemAdministrativeLocator, NULL, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID*)&pLocator);
           if (SUCCEEDED(hr))
           {
               IWbemServices *pServices;
               BSTR ns = SysAllocString(L"root\\WMI");
               hr = pLocator->ConnectServer(ns, NULL, NULL, NULL, 0, NULL, NULL, &pServices);
               pLocator->Release();
               SysFreeString(ns);
               if (SUCCEEDED(hr))
               {
                   BSTR query = SysAllocString(L"SELECT * FROM MSAcpi_ThermalZoneTemperature");

                   hr = pServices->ExecQuery(wql, query, WBEM_FLAG_RETURN_IMMEDIATELY | WBEM_FLAG_FORWARD_ONLY, NULL, &pEnum);
                   SysFreeString(wql);
                   SysFreeString(query);

                       hr = pEnum->Next(WBEM_INFINITE, 1, &pObject, &returned);
                       _com_error err(hr);
                       LPCTSTR errMsg = err.ErrorMessage();
                       qDebug() << QString::fromStdWString(errMsg);
                       pEnum->Release();

                           SysFreeString(temp);
                           if (SUCCEEDED(hr))
                           {
                               *pTemperature = V_I4(&v);
