I would like to thank Keith and Heather very much - and also Chris whitehead at Panasonic UK and Peter Mitchell at Panasonic Australia.
It is definitely a driver issue that XP is not allowing installation. I am not sure that we could do KeithB's solution - which definitely sounds the most straight forward - but we are doing it via manually over-riding xp device manager/driver updates.
There have been a number of steps in this - we now have Song Recorder working but not yet fully the Song Manager. When we do I will post the path - those that are published may not be complete at least that is the way it is looking for me.
Best
