D*ngle dk12

As i can understand , you mean the Company DESKey and the dongle is the
DK12 Dongle , right?
Also as i can understand , you are in trooble with an application that is protected with that dongle,right?

So , as i can remember , the programming team of DESKey is good enough
and has made a very excellent job about "binding" the EXE with the HASP.

So , if you are interested about how you can bypass this protection
first of all try to do it by yourself because out there (internet) there is no new tutorial material about DESKey dongles , or try to find the DESKey Protection Remover ,but i think this remover is very old...but try to find it..
maybe it helps..
