During the completion of the Configuration Wizard you receive an error: Unable to Communicate With The Web Server With Configured Settings.
The prerequisite checker didn't report any errors communicating with the web server when it was ran.

For Windows Server 2012 R2 Servers you can install this by running the following command from an administrative command prompt:
dism /online /enable-feature /featurename:IIS-ASPNET45
For Windows Server 2008 R2 Servers you can download the module from the link below.
