P3e Installation problem

Apologies if this subject has already been discussed.

I have demo copy of p3e
I have installed it ok but virtually every time I click on a menu option, i get a message "please wait while windows configures microsoft office 2000 premium"

if i press cancel a couple of times it sems to go to where I want to go in P3e, but it is frustrating more than anything.

is there a way to fix this without having to obtain a copy of 2000 premium? I currently have office 2000

thanks
