SQL Server 2012 setup fails on Windows Server 2008 R2 Core

Hi,

I have a WIN200R2 Core server on Hyper-V and I'd like to install SQL Server 2012 on it. I use the following command:

Setup.exe /qs /Action=install /Features=SQLEngine,IS,Conn /InstanceName=MSSQLServer  /SQLSYSADMINACCOUNTS="Contoso\kim_akers" /IAcceptSQLServerLicenseTerms

(This is from book https://www.microsoft.com/learning/en-us/book.aspx?id=16016 )

I receive the following error message:

'Object reference not set to an instance of an object.

Error result: -2147467261

Result facility code: 0

Resul error code: 16387'

Could you suggest a resolution?

Thanks.

P.
