Problem with Bitlocker in MDT2012u1

Hello ,

I'm trying to deploy in MDT 2012u1 Windows 8 Pro with Bitlocker enabled, but bitlocker section  is not displayed in Task Sequence.

I'm changed ZTIutility as described in: http://www.vaughnemiller.com/2013/01/23/displaying-the-bitlocker-wizard-pane-with-windows-8-pro-and-mdt-2012-update-1/

but without success

Any solutions??
