Installation Issues

I’ve been very eager to try out NLP with my new scanner, however, I haven’t even been able to get the trial to work in Lightroom. When I’m in the plug-in manager window in Lightroom, it says the NLP plug-in is installed but not working. Does anybody know how to remedy this issue or what might be causing it?

Do you still have the issue? Which versions of Lightroom, NegativeLab and macOS do you use?
