Hello,
Sorry to hear you are having issues. Not really sure if you meant Virtual Machine, no issue for me to activate Fences on my Virtual Machine. Need to know more.

1) Did you purchase Fences through Steam or Stardock directly?

2) Have you successfully activated it in this system or any other system before?

3) If the Email used to activate it linked to your purchase. ie. If you paid using paypal. The email link to the activation key will be the email that link to the paypal.

Thanks
