I've just got FrontPage 2000 but for some reason can't get it to set up on my
computer, I keep getting a message saying "setup failed to locate a valid
qualifying product on your machine. Please select the drive where a
qualifying product can be found". What do I do now? I have windows 2000 and
when I click on the "start" button down the left it says windows 2000
professional. Can anyone help please?

You have probably downloaded umm bought a upgrade copy and just having a copy of windows isn't a valid upgrade path.
