ASP.NET page published on IIS 7 reports 404 - asp.net

Question

I am trying to get an ASP.NET MVC 4 page working on a productive system. On my local system with IIS 7 and Windows 7 Professional everything works fine.
Productive system:
Windows Web Server 2008 R2 64 bit
IIS 7 with .NET 4
For the page I created a new IIS site. For the site i created a new application pool which uses: .NET Framework v4.0.30319 and integrated mode. For the application pool the flag for 32 bit applications is activated, because i need to run my application as 32 bit app.
When I access the page via
https://localhost:12345/PageName
i get the error message:
(I translate it from german:)
Server error in application /PageName
The resource could not be found
Description: HTTP 404. The resource or a dependency could not be found...
Requested URL: /PageName
Version: .NET 4.0.30319; ASP.NET 4.0.30319.1
The routing table:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute("Default", "{controller}/{action}/{id}", new { controller = "MyController", action = "Index", id = "" });
The Index method of the controller looks like this
[ValidateInput(false)]
[RequireHttps(Order = 1)]
public ActionResult Index(string method, string chapterId, string sessionKey, string cn, string ui, string pw, string ProductNumber, string DocumentData)
{
// something...
}
web.config
...

</handlers>
</system.webServer>
For debugging purpose I added the http://haacked.com/archive/2008/03/13/url-routing-debugger.aspx to the Application_Start function of the global.asax file.
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
// added call here
}
The route is solved correct. --> Controller = "MyController", Action = "Index", Id = ""
