When the application runs it asks to install titanium proxy certificate . I want certificate can be installed once for one machine not for every user . How can i do this

This is how i am starting the proxy server

    proxyServer = new ProxyServer();
    proxyServer.CertificateManager.CertificateEngine =          Titanium.Web.Proxy.Network.CertificateEngine.DefaultWindows;
    ExplicitProxyEndPoint explicitEndPoint = new(IPAddress.Any, 8000, true);
    proxyServer.AddEndPoint(explicitEndPoint);
    proxyServer.Start();
    proxyServer.BeforeResponse += OnResponse;
    proxyServer.SetAsSystemHttpProxy(explicitEndPoint);
    proxyServer.SetAsSystemHttpsProxy(explicitEndPoint);
