SSL certified opening on client from the server

Question

I have to use an SSL certificate on the client, using a web page in ASP.NET which is found on an IIS server. To do this I try to open x509store. Everything is fine on the development computer, but if I publish on the IIS server I receive the error: The current session is not interactive. I tried to change your user profile on true, but it doesn't work. I'm not very practical of asp.net and so I don't know what to do, can you help me? Sorry if I'm not very clear, but I can add any information you ask me. This is the code I use and that works on my PC.

        public static X509Certificate2 GetCertificate()
        {
            X509Store x509Store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
            X509Certificate2 certSelected = null;
            x509Store.Open(OpenFlags.ReadOnly);

            X509Certificate2Collection col = x509Store.Certificates;
            X509Certificate2Collection sel = X509Certificate2UI.SelectFromCollection(col, "Title",    "Message", X509SelectionFlag.SingleSelection);

            if (sel.Count > 0)
            {
                X509Certificate2Enumerator en = sel.GetEnumerator();
                en.MoveNext();
                certSelected = en.Current;
            }

            x509Store.Close();

            return certSelected;
        }
