Nuendo 1.6 'No Protection Device 'connected

Hi all,
Can anybody help me out ?

Friend of mine owns the official licensed Nuendo 1.5 -1.6 discs…after moving to his new house , he connected back his windows pc with windows 98 on it and at starting up Nuendo , it says 'No Protection Device connected…He says he has NEVER seen a Dongle key attached to his pc…does it mean that his version came with the license on the discs ???

Please advise…

Impossible. There never was a Nuendo version which could run without an attached dongle.
