Version 2004
19041.1083
The update caused 4 out of the 8 SDI Outputs to no longer recognized for Decklink Quad 2.
I have tried with Desktop Video Setup versions 11.5.1 and 12.1.
I have uninstalled the Decklink Devices in Device Manager and restarted Windows 10.
I have "Run As Admin" for DesktopVideoUpdater.exe and that didn't work either.
Unfortunately, I can't restore WIndows 10 to a previous build so I need a solution that isn't rolling back WIndows 10 every time there is an update.
