Yes I am aware that each version requires it’s own unlock key, but what i’m saying I have cal term 3.17 that is updated with some fairly new engines, so basically there has to be a way to do that

That's because you have 3.17 with the new product info database included. Unless you actually work at Cummins, you can't use their update manager to activate Calterm. When I make a KG I modify a few dlls so that Calterm looks at my activation method instead of attempting to use it's own default one via LCT.

Although I will say this... If you use my LCT crack, you can then use LCT to activate Calterm. But that's a whole different story altogether.
