With the final ISOs that were available from Digital River, I'm pretty sure they could be activated/installed with OEM keys as well as with retail or volume keys. If you're dealing with a factory Windows 7 Pro downgrade from Windows 8/8.1 Pro, you won't have those keys and life gets more complicated.
