Just FYI... In case anyone else has the same problem...
Did an Vista to Windows 7 RTM (Ultimate) upgrade. VirtualCloneDrive was still there after the install but crippled (no right-click menu or drives - Only the options dialog).
Reinstalled 5.4.3.2 VCD over the top of the old and all came good.
Also Power DVD (BluRay) was locking up loading BDs. Installed latest update rebooted and that came good as well.
So a few things seem to be reset during Win 7 update.
Happy ending
