Ao usar o instalador off-line ( link ) para instalar o .NET 4.6 em uma máquina com o Windows Server 2012 R2 Core, o seguinte erro está sendo retornado:

Eu também tentei instalar o .NET 4.6 usando o chocolatey. O seguinte erro é enviado para o log gerado:

Eu posso instalar com êxito o .NET 4.6 na versão completa (gui) do Windows Server 2012 R2.
UPDATE : Depois de remover o recurso Interfaces de usuário-Infra da instância do Full Win Server 2012 R2, o mesmo erro é produzido como ocorre na instância do Core.
Ambos os servidores estão sendo executados como instâncias da AWS e usam as próprias AMIs da Amazon.
