SATA by any chance?
How is the drive configured and managed.
Just had the same problem with MaxBlast and had already been warned it would happen with Acronis.
I'm assuming that the OS works and all your files appear to be present
You may have to uninstall all the Office software from the original drive. Run the image to the new drive and then reinstall the Office software! The good news is you will probably find it reactivates without having to phone Microsoft.
I foud all other software except Firewall settings and Dantz Retrospect settings transferred perfectly.
Hope somebody finds you an easier solution!
