DECKLINK MULTIBRIDGE EXTREME Drivers

Dear people, I recently started using a second-hand BLACKMAGIC DECKLINK MULTIBRIDGE EXTREME, but I do not get any software for this product with Blackmagic support. I have tried with Multibridge 7.9.4 and DeckLink 7.9.4 but the installation does not work. who can help me with the right drivers? thank you in advance. Greetings Frank

Here is the manual of the multibridge.. Which came out in 2005.. The Pro will have followed that 1 or 2 years later.. http://www.broadcaststore.com/pdf/model/799292/multibridgemanual.pdf

But i think the software support on this device is long gone.. And might not even work under windows 7 or 10??? Not sure..

But maybe if you can find Decklink drivers of the 5 or 6 series you might be able to get it running..
