Going from .exe to .fla?

Ok, so a long time ago (like 6th grade) me and my friend did this project in flash about buddhism. Now I’m in high school and we have to do a project on buddhism again so I’m thinking that maybe I could just use my project from 6th grade. (hee hee) Now, back in the day, in order for us to get it on the school computers, we would have to make a “projector” .exe thing and put it on a cd. I have a Macintosh now, and I have the .exe, but I can’t view it. Is there any way I could decode it or something?

BTW, I’m using Flash 8 Pro.
