Desktop Video and Can't Detect Devices

Good afternoon all!
I need some assistance. I updated the Desktop Video Set Up to version 12.1.
With this, it can't see my:
Decklink Quad Card
Decklink 2 Duo Card

I am running it on a Windows 10 Pro System that exceeds the minimum system requirements.

I've even tried reverting to prior versions with no luck.

Can anyone walk me through the steps I need to take to get these cards back in line? I know I am missing something, but after pulling out my hair for 3 hours on this, I'm waiving the white flag.

Uninstall Desktop Video with the Windows Control Panel - Programs and Features panel.

Then look in the C:\Windows\System32\drivers folder for any of the following files:

decklink_drivers.png
decklink_drivers.png (8.68 KiB) Viewed 1565 times


If any of those are still there, delete them, then install Desktop Video 12.1 again, and hopefully it will be working.

Please let us know what you find.
