I've searched this quite a bit. I'm running 2.3.8 on a Windows 10 64-bit machine. I generated a key (a few times, actually) and have tried using the built in Load function from ForScan, by opening it in regedit, and by manually copy/pasting the key into the registry location. I've restarted the application, restarted the computer, and tried reinstalling. Nothing will make this extended license activate. Any ideas?

I've tried activating on another computer and it was just fine, of course. I can't figure out what would be wrong/different about my computer but any help would be greatly appreciated!
