The one I got had two lots of CDs - the Full Monty you were only allowed to use as demos for customers and the Full Monty you can use in Production in your own company.
Watch the EULA though. Whilst I'm sure the one I got was Perpetual for my own use, later EULAs seem to show that the license is only valid if you buy another action pack the following year/when the one you have runs out. Confused? Welcome to MS Licensing...
The good news is they take service packs etc and run as the real McCoy - that's what they are.
HTH.
