I have just received a 30 Day Trial copy of Office XP and I wish to try it out before I reinstall my OS.

Currently, I have Office 2000 Professional installed on my PC and I am running Windows 2000 Professional as my OS.

Besides doing the usual thing of having uptodate backups of all my email and documents, is there anything thing I should remember to do to help have a smoother installation of the Trial Version?
What are the problem(s) (if any and I'm sure there is) could I possibly encounter?

Thanks in advance for the responses.
