If you are installing the full GUI on your Server core 2012 and receive this error, it is an easy fix.   Install-WindowsFeature : The request to add or remove features on the specified server failed. Installation of one or more roles, role services, or features failed. The source files could not be downloaded.   This simply means that your installation files need to be made available to PowerShell to do this.  To correct this, insert your installation media or map a drive to the installation source on your network.  Now add he – Source parameter to your Install-WindowsFeature cmdlet pointing to Windows folder to complete the installation Import-Module ServerManager Imstall-WindowsFeature –IncludeAllSubfeature User-Interfaces-Infr –Source < SourcePath>

Here is one that I had not thought of.  I’m exploring some AD DS installation option for Server Core.  While looking around, I discovered that I needed to update my Help files.  No problem except you need to op PowerShell as an administrator.  From the command prompt, start was something that I had not done.   After some exploring I came up with this. Type PowerShell to enter a PowerShell session. Type Start-Process PowerShell –Verb RunAs and press Enter . No problems updating help now.
