Sorry I was away for a while.
Thank for the replies.
To answer to Ror, OpenOffice is good but does not open complexe word document proprely and very unfortunately most people are more likely to be running Word than OpenOffice.
I also was aware of crossover office, but the turn off about it is the price. It's more than $0
The thing is that I already got Word working under linux. I can easily launch it through the terminal. What I'm trying to do is open it up through a launcher from the panel bar. So far all my attempts have failed.
