i have the original office home and student 2007 cd am trying to install it to my laptop sony. windows vista but every time it asked me for the key i typed it but in vain it keeps saying the key is incorrec. verify that you have the correct key then retype it. am saying the truth if i told you that i've trying this for more than one year, i took the laptop and the cd to store where i purchased the product, they said to me that i have to take it to sony centre and when i took it to sony they also told me that it's the store responsibility to install the office properly.but what they did then, sony installed the trial version and said that they fixed the problem but in fact they didn't. now, please i need urgent help. you can't imagine that one purchased a new laptop with office original cd a year and three months ago and couldn't use it till now.
