Not sure what Qualiparc is and what it wants, but..
There are two entries in the bios:
The first one is computer UUID (could be obtained with command "wmic path Win32_ComputerSystemProduct get UUID") - it is 16-byte number
The second one is computer serial (could be obtained with "wmic bios get serialnumber") - it is just a string, without any constraints. Many real hardware vendors don't supply it at all. Parallels forms it as "parallels-XXXXXX" where XXXXXX is text-representation of UUID.
May be you could use the plain UUID for Qualiparc. But not sure.
