Hi Graham

You probably just need to do this:

1: Run BiaB as Administrator (right-click icon on desktop (1) and select Run as administrator(2) ). On mine I set it to always run as Administrator. This is done through Properties > Advanced (3)

2: Turn UAC to off (lowest settings). This is how I always set my systems. I personally never use UAC. This is done from the control panel. Enter letters UAC (A) then click the Change User Settings (B). Set to Never Notify (C) and press OK (D)

The feature you need to add should then work without any issues (Restart BiaB of course)
