I followed a link on another thread (which seems to have been deleted) and there it was.
I haven't tried it, so I can't vouch for its effectiveness.
I deleted the CP, before I tried to "Upgrade" the DP.
Turns out that you can't perform an "Upgrade" on a VHD.
No real loss as the DP works OK and I can't abide using an OS that won't install my sound driver (no music or videos).
