Hi wila,
thanks for taking the time to reply to me.
Sorry I guess my first post was incorrect.
The solution WAS hosted directly on Windows (XP), and accessible via network.
Since the first hard drive died, it has been re-installed under windows 7. However, given certain network limitations for Windows Sharing, called OPLOCK (Opportunistic Locking and Read Caching on Microsoft Windows Networks), my IT guys moved it to Ubuntu via VMWARE workstation.
The license works fine for the host OS (windows 7), but not for the virtual OS (Ubuntu).
There is no way to tweak the UUID to my needs?
Thanks again for your help,
Ben
