I received the activation card in transparent bag sealed with tape stuck on the key, I was worried me from the seller who confirmed to me that the product was an original. Today I try to activate the product for the first time and this activation is refused by Microsoft with the message that the number of activations reached the limit, who bought the license last year, it is too late to challenge the purchase, it only remains me to advise against buying any product from that merchant.
