Provisioning BITLocker with Windows to Go via SCCM2012

Question

Hello,
I am following this document http://technet.microsoft.com/en-us/library/jj651035.aspx to provision Windows to go via Pre-Staging.
The instructions on what to put in the pre-start command is a little wooly, as best I can make out, I am pasting this directly in in prestart command window:
dim osd: set env = CreateObject(“Microsoft.SMS.TSEnvironment”)
dim logPath
logPath = env(“_SMSTSLogPath”)
env(“OSDBitLockerPIN”) = "password"
However, the task sequence falls flat when running the Bitlocker to go package, looking at the logs I see:
Failed to find Passphrase
I am running the package after the 'Configure Windows and SCCM Agent' step; OC the machine re-boots into windows here so I am not convinced it is the right place to call the package.
Can someone who has done this before give me sa quick hand please :)

Hello, any simple explanation for this? I´m running osdbitlocker_wtg.exe during TS in OSD, and before enabling bitlocker, I import all EVE reg settings which I exported from Bitlocker Group Policies. With those Group Polices, I´m able to enable bitlocker
manually on a desktop on a WTG USB stick.
