Silent install vi SCCM for Bluetooth Drivers and application for E6420

Hi,
I have integrated the drivers for the e6420 and am reasonably happy.
For the Bluetooth module I need the application installed also.
To do this I have created a Hardware based application using R293053.exe using the /S switch. If I install this manually, there is no issue. As long as the WIFI switch is turned on, it installs.
If I use the Task seq it errors out and when I log onto the laptop as myself I see a "windows setup encountered an error" message. I have grabbed the H and M dmp files and the accompanying text files.
SCCM error message below

Can anyone shed light on what I am missing?
