the final (or close to it) "Educational Version" disc had both the Apple and Windows versions on it. if you bought the retail version at the time, there was no windows version included.
mine says Appleworks 6, Educational Version, Version 6.2.4, and is dated 2002.
works great, use both versions, haven't tried under vista, but runs great on everything else windows. only downside is that the software is getting tough to find nowdays!
