Hi T-Man and sdrohan.
No luck, still not activating.
1. First I deleted from C:\ProgramData\Stardock Fences 3 and Fences 4. Those were the only two showing (not 5).
2. Tried activating; did not work.
3. Uninstalled older versions, 4 and 5 were listed. Clicked on 4 to uninstall and it started uninstalling v5. Here's a video of the process:

I did not select to 'remove settings,' and I had some errors about DLL's in use. I ended up Ignoring those, as shown in video.
4. Rebooted, and checked if Fences was running in Task Manager. It was not.
5. Reinstalled v5, and activation failed. Note that no license.sig was created in the ProgramData folder, in fact, there is nothing there.
