Dunno if Works will install in Win 7, but if it doesn't you could try
installing and running it in compatibility mode for XP (that got me out
of trouble a couple of times) or if you have Win 7 Pro you can set up a
virtual Machine for XP and run it inside the VM (which also got me out
of trouble with some older software). I don't think the Win 7 Home
version has the VM stuff.
According to this wiki:
https://en.wikipedia.org/wiki/Microsoft_Works
Works 9 is compatible with Vista, so there's a good chance it'll work
with Windows 7 which is basically Vista done properly.
