Query: Don't buy this Product!

I bought it for 45 USD in Turkey. After some installation, the product did not accept authantication because of "you aproached to the limit of your installation number". What a silly condition! If I bought it, I want to be able to install it on the same computer, whenever I want it. I dropped it to trashcan and I have downloaded "Avast! anti virus programme home edition" for free! Additionnally It is better than Norton.
