N7 and decklink sdi problem

I am using Nuendo 7.0.30 and decklink sdi pcie on my Windows 8.1 PC. I have installed Desktop Video Driver 10.5 . But when I try to setup Blackmagic Decklink it doesn’t show up in Video player Device window. How can I fix that?


This is how it should look like.
Check the install again. Check if the “Blackmagic Design Control Panel” is to be found in the control panel.
Etc …


Thank Fredo you for reply, but the problem is solved! Use in regional and language settings on Windows 7 or 8 tab “English” (only with ‘dot’ not ‘coma’)
work on win x64, N7 x64.
