Bought it and after a while i found out how to open. Works good!

I had problems using this but asked support and they helped me to activate it, key worked as said. Thanks.

Δούλεψε μια χαρά στο macbook. Σε περίπτωση που έχετε άλλο παλιότερο συνδεδεμένο account είναι εύκολο να το αποσυνδέσετε και να το συνδέσετε μετο κλειδί αυτό μέσω του επίσημου remove office account tool της MS.

Excellent! Download the file, run the installation, digit serial code and boom! Ready to go! Serial code was immediately available after payment! Great Job!
