I installed it when I started school in the spring of 2010. I know they discourage you to resell it, but I'm paying a lot of money to attend this school and it's mine.
I got it for school last year. I pay a ton of money to go to this school, including for the cd's. They are mine, I have installed the program, now I'm getting something back.
Ya you could have covered the last 4 digits or something. Posting that key could have been a mistake. If it gets flagged from overuse by Microsoft, it will become inactive. Leading to a worthless copy of office unfortunately.
O, and if I recall from when I had a student edition for school, i believe you HAVE TO have a .edu email address to use when you go to activate the key. Thats the reason they sell this copy so cheap or whatever, cause its for students. Getting a .edu email is fairly simple, im just letting people know so they arent surprised.
