Using x86 DLL in an unreal engine Win64 C++ class - c++

Question

I have written code in a .NET Framework C++ file. The code uses the Articares DLL to connect with the device through an IP address. Where instance is simply creating an instance of the classes I want to use from the DLL. instance.EstablishConnection() is the function i want to call from the class.
The below code works perfectly in x86.
#include "pch.h"
#include "windows.h"
#include <iostream>
#include <chrono>
#include <thread>
#include<cstring>
#include <vector>
#include "Complex.h"
using namespace System;
using namespace Articares;
using namespace NLog;
int main(array<System::String^>^ args)
{
//Creating instances of the classes ----------------------------------------------------
Articares::Core::ArticaresComm instance;
Articares::Core::HMANData instance2;
Articares::Core::TargetParams instance3;
//Connecting to HMan -------------------------------------------------------------------
instance.EstablishConnection("192.168.102.1", 3000);
std::cout << "Connection with HMan established\n";
return 0;
}
However, i want to be able to use the DLLs in the unreal engine C++ file to replicate this code i have written.
But the error name must be a namespace name appears when i try to declare the DLLs in the unreal engine C++ file.
Could anybody tell me how to fix this problem to be able to use my x86 DLLs in the unreal engine C++ code?
Thanks.

Are you using C++ DLL or . NET DLL?
For C++ DLL, you need to add dependencies. Walkthrough: Create and use your own Dynamic Link Library (C++)
For .NET DLL, You are calling managed code in unmanaged C++.
Use Exposing .NET components to COM
For your reference: using c# dll in project c++
