I am trying to install SQL Server 2012 Native Client through Endpoint Central deployment and it is failing with fatal error. I enabled logging and can see it is failing on accepting a licence agreement; in the log file it has

"The required IACCEPTSQLNCLILICENSETERMS=YES command-line parameter is missing."

In all the documentation I have read it says MSI files are installed silently by default and you cannot add switches.

How can I get this package to install either silently or by specifying the missing parameter ?
