I am trying to install SMTP Server feature in Windows Server 2012 R2. I am using "Add Roles and Features Wizard". After clicking the install button, it shows red circle with white "x".
I assume that it means that installation failed. However, I cannot find any reason why it failed. I've also checked Application, Setup and System logs in Event Viewer. But there is no record regarding the SMTP Server installation.

Try install it via powershell:
Add-WindowsFeature [name_of_feature]
This case: Add-WindowsFeature SMTP-Server
