I do not clearly undertsand if the Upgrade of my Fences 3 product through "Own a prior version of Fences?" will allow me to install the new Fences 4 on my 3 computer like with my Fences 3 product. following the link below, i'm eligible to Fences 4 upgrade.
But in the FAQ https://forums.stardock.com/508196/fences-4-upgrade-faq
How does this affect the Fences 4 product in Object Desktop?
Fences 4 will still have 5 concurrent activations as do all the other member products.
If I purchase Fences 4, can I get more licenses at a discount?
Yes, once you purchase Fences 4 (or any Fences 4 product), you will be able to get additional licenses at a discount using the 'upgrade' link on the product page(s):
So i'm not sure that the Fences 4 upgarde will provide me the 3 install capability.
