Lost of activation after windows 11 migration

Since my migration from win 10 to win 11, I lost my Nik collection activation and I can’t no more activate it because the activation server is not available…so blocked with my sofwares…
I could do the activation for ViewPoint and for Photolab, I could use it without any activation lost !!!
I’m waiting for a support response…

Manage your licenses on Identifiez-vous

I’m not sure that Nik7 is visible, but you can always try.

Thanx Platypus for this link but even by deactivating, the server still does not respond

With Photolab, the license is automatically using 1 credit licence for windows 11 along the old win 10 licence without any re-activation. But it seems that Nik collection does not run the same way or same server because I could activate the ViewPoint without any issues and Filmpack does not ask me anything…

Look at this thread, it helped me: Nik Collection 8 - Impossible to activate

Thanx adi99, I also found it, and after having deleted the nikcollection7.key located in
C:\Users[Your Computer Login Name]\AppData\Local\DxO\Licences
I could enter in a new activation window. I filled in the key form and now it’s OK !!!

So this the way to resolve this windows 11 Upgrade deactivation with Nik Collection 7 AND 8 !!
