Converting FLA CS3 to Flash 8

I have a issue that is a bit complicated. I worked on a project at some company using CS3 on OSX. I took the files home to work on, however I run a PC with windows 2000. I tried opening the FLA in Flash 8, which, as i guessed didn’t work. Obvious solution: install CS3… however CS3 won’t install on platforms older than Windows XP.

At this point I’m trying to figure out some kind of solution.
Is there a way to bypass the windows xp requirement in the CS3 Installer?
Can I convert the CS3 FLA to a usable flash 8 version?

Any help would be greatly appreciated…
