Before applying  runAllManagedModulesForAllRequests  true   gt    consider the link below that suggests a less drastic alternative   In the post the author offers the following alteration to the local web config      lt system webServer gt       lt modules gt       lt remove name  UrlRoutingModule-4 0    gt       lt add name  UrlRoutingModule-4 0  type  System Web Routing UrlRoutingModule  preCondition      gt       lt  modules gt    http   www britishdeveloper co uk 2010 06 dont-use-modules-runallmanagedmodulesfo html

There is a Refactor -- gt  Rename Bug in Visual Studio 2012 that wrongly renamed the  id  inside the literal string value of the url parameter in my RouteConfig cs  This caused a 403 14 on a fresh and otherwise correct setup in both Windows Server 2012 and Windows Server 2008 R2   routes MapRoute      name   Default       url    controller   action   id        defaults  new   controller    Home   action    Index   id   UrlParameter Optional        was changed to  routes MapRoute      name   Default       url    controller   action   renamed text        defaults  new   controller    Home   action    Index   id   UrlParameter Optional

You can also get a 403 if when testing with dev server you are using integrated pipeline and then install as classic pipeline mode on your live IIS 7 5 web server  also I was missing my app data folder which also was required

Error 403 14 is the HTTP error code for not being allowed to list the contents of a directory   Please be sure that    You have setup the website as an application in IIS  You have  NET 4 5 installed on the server     You have set the application pool to run the proper version of the      NET framework  ie  it is not set  to  NET 2 0         You are using the integrated pipeline on your application pool  NET 4 5 is actually registered in IIS   Please see this post for a similar issue resolution   Usually  a and d are the biggest issues surrounding MVC deployments to IIS

In my case the issue was caused by custom ActionFilterAttribute which was a kind of global filter attribute  The attribute instantiated a service through Autofac but the service crashed in constructor   public ActionFilterAttribute          service   ContainerManager Resolve lt IService gt        public class Service  IService        public Service                 throw new Exception  Oops

I had set the new app s application pool to the DefaultAppPool in IIS which obviously is using the Classic pipeline with  NET v 2 0   To solve the problem I created a new App Pool using the Integrated pipeline and  NET v4 0  just for this new application and then everything started working as expected   Don t forget to assign this new app pool to the application  Select the application in IIS  click Basic Settings and then pick the new app pool for the app

the one i see more frequently recently is IIS and allowing 32bit applications to run   Is this what you have tried  otherwise we need more information about production and dev server versions

I m running Windows Server 2012 R2 on Azure and ASP NET 4 5  IIS 8  I solved this problem by uninstalling all of the ASP NET items in Programs and Features  then reinstalling ASP NET like this with Server Manager using Add Roles and Features  picked Role-Based or Feature-Based installation  picked my server  and then for Select Server Role picked Web Server  IIS  Web Server Application Development  then clicked ASP NET 4 5  confirmed installation of a prerequisite  and then reinstalled ASP NET 4 5   My previous searches had lead me to believe that the problem actually stems from a registration problem with ASP NET  With earlier versions of ASP NET  there is actually a utility that you can run to register ASP NET without reinstalling  but that doesn t seem to be available any longer

If you re running IIS 8 5 on Windows 8  or Server 2012  you might find that running mvc 4 5   net 4 5  doesn t work in a virtual directory  If you create a local host entry in the host file to point back to your local machine and then point a new local IIS website to that folder  with the matching host header entry  you ll find it works then

Perhaps    If you happen to use the Publish Wizard  like I did  and select the  Precompile during publishing  checkbox  like I did  and see the same symptoms       Yeah  I beat myself over the head  but after unchecking this box  a seemingly unrelated setting  all the symptoms described go away after redeploying   Hopefully this fixes some folks
