Validating Old CD Key

[RKBock]

I have a retail-bought CD version of the HoMM V Gold Edition. Unfortunately, since CD players are going the way of the Dodo, my new PC does not have a CD player, which is why I wanted to simply use the Keys that I have, to add the game to my steam library and simply download it.

Now, unfortunately, the keys have the format:
HM5-XXXX-XXXX-XXXX-XXXX
H5A-XXXX-XXXX-XXXX-XXXX
H5B-XXXX-XXXX-XXXX-XXXX
And thus steam does not recognise them. Is there any way for me, except by buying them again, to add them to steam in another way or otherwise download the game legally?

Nvm, I wrote the Ubisoft Support and they activated the game on their launcher for me.
