Actually, Office 2000 installs and works perfectly fine on Windows 95. Furthermore, it only needs Internet Explorer 4 or higher.
However, if you are look for a Viewer for Power Point Presentations try:
PowerPoint Viewer 97 (2002 Release) at
http://office.microsoft.com/downloads/2002...2/ppView97.aspx
(Note that it only allows you to view presentations, it doesn't allow you to create or modify them.)
