Hi,
Thanks for the reply.
I had a doubt about the nVidia card, so I changed it to an ATI 9600 earlier and subsequently reached the AV Wizard.
Having gone through the wizard, a message was displayed that some automated setup would run for approximately 15 minutes.
However, during the auto process, the following message was displayed:
Orbiter failed to load the transparency. Please check if the transparency manager is running.
Unfortunately, now the set-up won't proceed, but I can't see how to turn on the transparency manager.
Suggestions please...

Thanks.
