I am assuming you guys pushed out an update. My version of fences is now 3.0.9.11 and it seems the functionality is restored because it actually asked for my product key. Previously your installer never did, so you can mark this as fixed.
It's a corporate environment so 1909 would be as current as I can get for the next year.
Here is a link to a video rather than trying to describe my problem. Any help would be most appreciated. In short same software on windows 10 1803 works fine, but on windows 1909 it doesn't work. https://youtu.be/bZYPwT1cfiU Here is event viewer, pretty much get this same error when trying to perform configure fences.
