Installing/Using Office Xp Pro On Windows 7 OS

1) Is anyone doing this &/or know if it will work alright (as in not cause Win7 to crash or otherwise cause a problem)? Since I already have XP Pro and am perfectly happy with not having some of the extra gadgets that come with the newer Office (along with the newer price ) I'd like to just use what I have...

2) I've been told (by one person) that it will be fine and to just make sure to "uninstall" any Office programs on my Win7 computer before installing.

3) However, I've also been told (by someone else..a computer store employee) that it won't work.

I'd really like to get Word, Excel, and Pwr Point back up and running. This computer was purchased "with" Windows7 and a trial version of Office.
