about QM3 Some suggestions

LA uses the .NET `HttpClient` with default settings. On my test Windows 7 it works. Changing the security protocol type is possible, but not recommended. On that rare computers where fails, it's better to show a dialog with "download manually" instructions.

LA uses this code. You can try it in a script.

Code:

//Get the download URL of the last sqlite version for this OS. This way is documented in https://www.sqlite.org/download.html.
var html = internet.http.Get("https://www.sqlite.org/download.html").Text();
//print.it(html);
if (!html.RxMatch(@"(?s)<!-- Download product data for scripts to read\s+(.+)\s+-->", 1, out string csv)) throw new AuException();
//print.it(csv);
var x = csvTable.parse(csv);
string s = $"sqlite-dll-win-{RuntimeInformation.ProcessArchitecture.ToString().Lower()}";
string url = x.Rows.First(o => o[2].Contains(s, StringComparison.OrdinalIgnoreCase))[2];
url = "https://www.sqlite.org/" + url;
print.it(url);

//Download the zip.
var bytes = internet.http.Get(url).Bytes();
print.it($"OK, size={bytes.Length}");

With changed security protocol it would be

Code:

using System.Net.Http;
using System.Net;

using var handler = new SocketsHttpHandler {
    SslOptions =
    {
        EnabledSslProtocols = System.Security.Authentication.SslProtocols.Tls12,
    },
    AutomaticDecompression = DecompressionMethods.All
};

using var http = new HttpClient(handler);
http.DefaultRequestHeaders.Add("User-Agent", "Au");

//Get the download URL of the last sqlite version for this OS. This way is documented in https://www.sqlite.org/download.html.

var x = csvTable.parse(csv);
string s = $"sqlite-dll-win-{RuntimeInformation.ProcessArchitecture.ToString().Lower()}";
string url = x.Rows.First(o => o[2].Contains(s, StringComparison.OrdinalIgnoreCase))[2];
url = "https://www.sqlite.org/" + url;
print.it(url);

//Download the zip.
var bytes = http.Get(url).Bytes();
print.it($"OK, size={bytes.Length}");
