You can try it, but I doubt it, it was released for Win 98. I wouldn't expect Access or Outlook to work and you could have a problem with macros in Excel.
You can download Open Office for free it's like MS Office and more up to date.
Thanks for your answers. I tried it, and had limited success. Excel worked as it always had in all versions up to Vista, and continues to do so. Word on the other hand, worked but in a slightly different way it had up to Vista. In Windows 7, while it worked, it was not so user friendly. If you clicked on a Word file in Documents it failed to open. But it worked normally if you selected File, Open and selected a file from the list in Documents. So I have uninstalled Office 97 Pro and bought MS Office 2007 Home and Student which does all the things I want it to do. PowerPoint in 97 also worked. But I never tried Access or Outlook in 97 as they are not programs I use.
