Hello,
Sorry to hear you are having issues. If you have installed Fences properly, Fences.exe should be in this directory: C:\Program Files (x86)\Stardock\Fences. Are you looking in the same directory?
When you installed Fences.exe did you remember seeing any error message appear? And most importantly, did you reboot your system right after the installation finished?
Thank you,
