The tool was unable to install Application Server role. Web Server (IIS) role

While installing SharePoint 2013 onto Server 2012, I came across an error as “The tool was unable to install Application Server role. Web Server (IIS) role”. After browsing internet for resolution, I finally could resolve my issue. But while doing my investigation into the error, I came across posts where different people have tried different things to resolve the same error. I will try to collate those and post it in one single post.

Option 1 :

Go to Server Manager and click on Add Roles and Features

Select and expand Web Server (IIS) Role 

Select the IIS 6 Scripting tools under Management Tools within Web Server role

Click Next until the wizard finishes

Rerun the Pre-requisite setup and see if you have been able to resolve the error.

Option 2: (only for Windows 2008 R2)

Go to command prompt and run this command:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i –enable

Option 3:

Run powershell with admin priviledges

Run the following commands: (I mounted my Server 2012 ISO on D drive)

Import-Module ServerManager
