I installed it, I have not yet had time to use it. Very painful this installation: download the software, register at Microsoft, enter the key, plus install my antivirus that slowed everything and so I had turned off during the entire operation ... !! In addition it is not given and you have to pay 12 euros more if you want a backup copy. The price of the key, it seems more appropriate to me to offer us a usable cd to several items in the family ... (a floating license is more expensive). If I need another software, I will choose a CD. I hope that will use less tedious!
