Office 2000 installation on WIN ME.

I am trying to install Office 2000 Pro on a Clean install of Windows ME. Everytime I try to run the install program right at the beginning in the Office 2000 Setup Box it comes up with a message that says. “you must reboot your computer for installer to continue” I do this and try it again and walla, its says it again. I have tried two different CD’s same result. I was able to install Office 97 on the same machine however. Anyone have any ideas here?
