Menotu - very strange. I never got as far as the install - as soon as I clicked on 'Start' to begin it, I got that message. However, having read your post, I tried again. Clicked on 'Start', got the same error message once more. Even so, I rebooted. To my amazement, everything then worked - on both machines. Was I missing some direction? What was that about? Anyway, whatever - it's all running now. So - I don't know what you did but thank you.
