Debridging key

Hello, this is not a pirated software, but I want to reinstall it on another computer because I'm having problems with this one, and I can't find the sticker where the activation key was noted. The accounting department that sold it to me is asking me for around one hundred euros to give it back to me, so I wanted to know if it was possible to recover it from my first computer. Thank you.

Hi

It's not really Database, but still contact the seller or even the publisher (sometimes, the keys are generated by the publisher themselves).

Could you tell me if I can find the debridging key for Marco Polo on my computer?

Well, if it's not written on the box, it's dead.
Or hacked.
