Multiple errors on cloned hard disk

Hi
I am doing a favor for a friend. Her hard drive was failing so I cloned it using HD clone onto a new one.
Vista boots fine but none of the services seems to be running.

Upon starting you get the error message: windows cannot find c:\windows\SMINST\Components\scheduler\STService.exe


when I try to browse the files via windows explorer I get the error message "Class not registered"

When trying to open Word the error message:

Problem with shortcut "the windows installer service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance"

Basically besides the OS nothing can run

I tried running system repair off the vista recovery CD but it has not helped.

Any suggestions?
Thanks
