How to fix: Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list
I am configuring an MVC 3 project to work on a local install of IIS and came across the following 500 error:
Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list.
It turns out that this is because ASP.Net was not completely installed with IIS even though I checked that box in the "Add Feature" dialog. To fix this, I simply ran the following command at the command prompt
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
If I had been on a 32 bit system, it would have looked like the following:
%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i
My question is, is there a way to install IIS on a windows 7 box to use .NET 4.0 (MVC 3) without taking this extra step?

The accepted answer is correct, however sometimes you would get the "Aspnet_regiis.exe is not recognized as an internal or external command, operable program or batch file." error message.
To resolve it try the following:
Make sure that your .NET 4.0 installation is not corrupted (run the installer and 'Repair' it). There's also a chance it is not installed on your machine at all.
If you're sure you don't have .NET 4.0 installed and want to run it as .NET 2.0, try this:
If you see the message "Aspnet_regiis.exe is not recognized as an internal or external command, operable program or batch file.", switch to the C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Aspnet_regiis.exe -i at the command prompt.

I found the articles to fix this issue by simply run the following commands at the command prompt:
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
If the system is 32 bit, it would have looked like this:
%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i
But, when I tried to execute these commands using a command prompt, I got the following error/warning message:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis.exe -i Microsoft (R) ASP.NET RegIIS version 4.0.30319.33440 Administration utility to install and uninstall ASP.NET on the local machine. Copyright (C) Microsoft Corporation. All rights reserved. Start installing ASP.NET (4.0.30319.33440). This option is not supported on this version of the operating system. Administr ators should instead install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Win dows Features On/Off" dialog, the Server Manager management tool, or the dism.exe command line tool.

To fix this on a Windows 8.1, I would suggest to do the following thing.
Solution:
Goto: Turn Windows features on or off -> Internet Information Services -> World Wide Web Services -> Application Development Features -> Enable ASP.NET 4.5
This should resolve the issue.
To solve the issue try to repair the .net framework 4 and then run the command
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
I would also check the obvious first: that the application pool is set to the correct framework and that your IIS application actually points to the folder where you put your files
