Fences 3 is only free if you bought Fences 2 within 90 days of the release of Fences 3.  Otherwise Fences 2 users can upgrade to Fences 3 for $5, see the link "Own Fences 2?" at the bottom of this page:

https://www.stardock.com/products/fences/download.asp

If you want to stay with Fences 2 at this point, you would uninstall Fences 3, reboot, reinstall Fences 2 and activate it.  You would probably want to take snapshots and back them up first, if you have them backed up from immediately before you installed Fences 3 that would probably be better.

That is not right. I haven't been able to get Fences 2 to work on Windows 7 yet. I mentioned this earlier, but got no reply. I am now trying Fences 3 and it is doing the exact same thing - can't move icons on screen (had to disable it to do that), and it randomly moves icons to where it thinks they ought to go without my intervention.

So Fences 2 & 3 do NOT work on my Windows 7 64-bit machine. I have tried them on my laptop as well, and I get the same result...they do NOT work properly.
