---------------------------
Virtual PC
---------------------------
Virtual PC has detected an invalid or missing Product ID.
A valid Product ID is required to operate Virtual PC. Please
re-run the Virtual PC installer and enter a valid Product ID when
requested.
---------------------------
OK
---------------------------

The solution is basically as described here, except I had to create the registry keys and values as they were missing on my machine.
