Same here with DeckLink Duo 2 on Windows. It's still in device manager but with warning sign. Seems to be an issue with the signature of the driver BlackmagicIO.sys in 10.9.9.

Same here with my Decklink 4k, too. Only 10.9.5 drivers recognize my device under Windows 10.

Can you disable secure boot and see if this persists?

Disabled Secure Boot and did a fresh Windows install. Now 10.9.9 is working. But why was is working with 10.9.7?
