ASP.NET MVC on IIS 7.5

ASP.NET 4 was not registered in IIS. Had to run the following command in the command line/run

32bit (x86) Windows

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

64bit (x64) Windows

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir

Note from David Murdoch's comment:

That the .net version has changed since this Answer was posted. Check which version of the framework is in the %windir%\Microsoft.NET\Framework64 directory and change the command accordingly before running (it is currently v4.0.30319)

One more thing to make sure you have is the following set in your web.config:

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/> 
</system.webServer>

Make sure you have is the following set in your web.config:

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/> 
</system.webServer>

Better solution:

Even though above solution works absolutely fine, it can cause other problem as it runs all your registered HTTP modules on every request (even on every request of .jpg .gif .css .html .pdf etc) and it is obviously waste of resource. Instead

<system.webServer>
<modules>
  <remove name="UrlRoutingModule-4.0"/>
  <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" preCondition="" />
</modules>
</system.webServer>

Make sure preCondition attribute is empty means it will run on all requests. [Read more](http://www.britishdeveloper.co.uk/2010/06/dont-use-modules-runallmanagedmodulesfo.html,"Read original post")

Another reason why someone might get this error is if the file Global.asax is not in the root folder anymore.

I was also receiving this error and discovered that "HTTP Redirection" was not turned on in Windows Server. This blog post points this out as well: http://blogs.msdn.com/b/rjacobs/archive/2010/06/30/system-web-routing-routetable-not-working-with-iis.aspx

Sweet Jesus. I tried all of the above things (but found my settings identical). YET ANOTHER SOLUTION if you are having issues:

http://support.microsoft.com/kb/980368

Try installing this KB for your system. If you are seeing 404s it might be because you don't have this update -- and the isapi module just isn't getting found and there's not a lot you can do about that without this!

Also u can switch AppPool to Integrated mode. Thnx to Michael Bianchi (https://stackoverflow.com/a/7956546/1143515), I only want to underline that.

For me on an Azure Server 2012 R2 IIS 8.5 VM with an Asp.Net MVC 5 app (bin deployed MVC 5) I had to do the following from an elevated cmd prompt even though I had 4.5 already installed:

dism /online /enable-feature /featurename:IIS-ASPNET45

Source: http://support.microsoft.com/kb/2736284

I also brute force installed all IIS features with the following PowerShell:

import-module servermanager
add-windowsfeature web-server -includeallsubfeature

Source: http://www.iis.net/learn/install/installing-iis-85/installing-iis-85-on-windows-server-2012-r2

Now my app is working.

We had a MVC application moved to a new server. .NET 4 and MVC 3 was installed, but we still got “Error 403.14″. In this case, this meant that IIS did not understand that it was dealing with a MVC application, it was looking for the default page.

The solution was simple: HTTP Redirection was not installed on the server.

Server Manager – Roles – Web Server (IIS) – Roles Services – HTTP Redirection: Not installed. Installed it, problem solved.

Also if your app is precompiled you should have

PrecompiledApp.config

in the root folder of your app otherwise you could get HTTP Error 403.14 as well.

Another possible solution, if you move around your global.asax, make sure the markup points to the correct MvcApplication class. Hopefully this will save someone in future.

I had used the WebDeploy IIS Extension to import my websites from IIS6 to IIS7.5, so all of the IIS settings were exactly as they had been in the production environment. After trying all the solutions provided here, none of which worked for me, I simply had to change the App Pool setting for the website from Classic to Integrated.

I have met the same 404.14 problem suddenly. Finally the problem had been fixed by unchecking "precompile while publishing" in the publish profile settings.

I altered my default route at one point from:

routes.MapRoute(
"Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = UrlParameter.Optional }

To:

routes.MapRoute(
"Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index" }

Which gave me your error. Glad someone mentioned routing because I probably would've been on this forever.

In my case ASP.NET 4.5 is not installed on the server so installing ASP.NET 4.5 fixed the issue.

Do the same as in picture for windows 32 bit

Just make changes in 64 bit as framework64 instead of framework only Than go to iis and refresh the site If u still got some error make changes in application pool

I had another problem that led to this issue.

I had ensured my app pool was running .net 4 in integrated mode

I had run aspnet_regiis.exe -i

I had checked folder permissions were set correctly for the account running my app pool

None of these things worked. It turned out that in my web.config under system.webserver > modules I had the following:

<remove name="WindowsAuthentication" />

Obviously this removed the windows authentication module which seemed to somehow knock everything off kilter.

I hope this helps someone, as this cost me most of an evening!

The UI is a bit different in the newer versions of Windows Server. Here is where you have to enable ASP.Net in order to get it working on IIS

Adding another solution for this issue.

in my Global.asax.cs file I had disabled attempted php files from being consumed by the MVC pipeline using the following:

routes.IgnoreRoute( "{*php}" );

I had done these previously in a MVC2 project and it worked fine, but doing this in my MVC 3 app caused the issue reported above.

Yet another reason this can happen - your RouteConfig.cs or WebApiConfig.cs are invalid.

In my case, I had a route defined as such (note the parenthesis instead of curly brace):

...
routeTemplate: "api/(something}"
...

Please note for Windows 8 users you need to add/remove windows components and remove the version of .net reboot then re-install in order to register it with IIS. I presume this happens if you get .net 4.5 from visual studio and install IIS afterwards.

As strange as it may seem, reinstalling IIS was what has worked for me, with the following command run from inside the .net version folder:

aspnet_regiis.exe /i

https://i.stack.imgur.com/wIqjT.png

When I first run this command, I begun getting the HTTP Error 403.14. But once I runned the command again it solved the problem.

Obs: Another thing I also did was to remove HTTP Redirect from the server features in Server Management screen before reiinstalling IIS. Maybe this also had an impact in solving the problem, but I am not sure. So, if reinstalling IIS still doesn't work, please try removing HTTP Redirect and try again. Hopefully it may work for you too.

To solve this problem without having to resort to 32 bit mode you will have to update the source code for this project

public static void RegisterUrlRoutesFromAttributes(RouteCollection routes)
{
    // Enumerate assembly for UrlRoute attributes.
    List<MapRouteParams> routeParams = new List<MapRouteParams>();
    AppDomain.CurrentDomain.GetAssemblies()
        .ToList()
        .ForEach(assembly => routeParams.AddRange(GetRouteParamsFromAttributes(assembly)));

I have raised this issue as a discussion on the discussion board at the IT cloud codeplex project.

http://itcloud.codeplex.com/discussions/262000

This worked for me and it might be useful to another one.

Maybe all components required are not present or/and not all are registered correctly. In order to solve this, try to uncheck all options inside Control Panel -> Turn Windows features on or off -> Internet Information Services -> World Wide Web Services -> Application Development Features, uncheck all options and recheck all then reset the IIS and check if the problem is solved.

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.

I created a new namespace (and therefore folder) identical to the route to a controller (e.g. MvcApp/Test/SomeClasses.cs and MvcApp/Controllers/TestController.cs). This resulted also in a 403.14!

For me, the solution was to add the NuGet package Microsoft.AspNet.WebPages (plus it's Razor and Infrastructure dependencies) to my web project.

Infrastructure had to be forcefully reinstalled as it was not added as a reference at first.

In my case .NET CRL Version in Application pool prppertires was set to No managed code (do not know why). Setting it to .NET CRL Version v4.0.30319 solved the problem.
