    System.IO.FileInfo file = new System.IO.FileInfo(System.Web.HttpContext.Current.Server.MapPath(System.Configuration.ConfigurationManager.AppSettings["FolderPath"].ToString()) + "\\" + "Default.aspx");
    System.Web.HttpResponse Response = System.Web.HttpContext.Current.Response;
    Response.ClearContent();
    Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
    Response.AddHeader("Content-Length", file.Length.ToString());
    Response.ContentType = "application/octet-stream";
    Response.WriteFile(file.FullName);
    //HttpContext.Current.ApplicationInstance.CompleteRequest();
    Response.Flush();
    Response.End();
    return result;        
}

                          success: function (result) {
                              alert(result.d);

Have you tried just doing a Response.Redirect() to the file instead?
