Although (or maybe because) Microsoft is making billions of $ a year as PROFIT from the Office suite (with profit margins > 70% or so) they aren't inclined to give it away. So no free downloads available. But OpenOffice is a good replacement (and I'm sure the same goes for the Corel Office suite, if you happen to have that).
Why don't you explain why Corel office isn't suited for what you want to do with it? Personally I use Outlook Express to view my email, but my children use IE or Firefox, because they have an hotmail-account. What do you want to do exactly, and what happens (error message and the like)?
And please don't forget to add capitals, comma's and full stops as Mark already suggested. It makes your message much more understandable for everybody but yourself.
