URLdownloadToFileW Doesn't download a file

I'm trying to download zip files from the internet using URLDownload But i get an output of 104 ASCII h but it doesn't download anything at all I tried using a vector but got an error saying doesn't match type const wchar_t*

Also what method would i go about finding a users username and saving it to there desktop for other people who decide to use my program. I want to create an installer for windows programs.

So that if i ever mess up my PC. I can run my script and download everything.

Another thing. Is there a way to create some kind of list of URLs to download without constantly having to enter a url. This is one reason i am using a class. So i can download multiple files.

Here is my code:

#include <windows.h>
#include <iostream>
#include <cstdio>
#include <vector>

namespace web {

    class Downloader {

    public:
        const wchar_t* URL;
        const wchar_t* dest;


    };
}

int main()
{
    web::Downloader download;
    web::Downloader* file{ &download };
    file->URL = L"https://github.com/Sycnex/Windows10Debloater/archive/refs/heads/master.zip";
    file->dest = L"C:\\Users\\file.zip";
    if (S_OK == URLDownloadToFileW(NULL, file->URL, file->dest, 0,  NULL)) {
        std::cout << "Downloading file : " << *file->URL;
        return 0;
    }
    else {
        std::cout << "err: " << *file->URL;
        return 1;
    }

    return 0;
}
