At the moment, Acronis seems to be my friend! The installation problem was overcome by disabling the Firewall (seemed a bit strange to have to do so, but..) and thus registration was permitted.
Have cloned a hdd successfully and pc has booted (after a little tweaking with the boot order, but only minor).
Acronis has done what Ghost 10 was unable to do. Thanks for the advice on that.
Have another query now but am about to post in a new thread.
Thanks to all for info / advice.
