Is it possible to export SWF image files?

I am using the older 18.0.02 version of animate, but cannot get the .swf export to work.

I have used Animate for illustration from way back in the Flash days as I have always found the drawing quality really useable. In the old days I always used to be able to export as a .ai file which I could then edit further in illustrator, and I'm sure I have in the past managed to export swf.

It's a real shame if there is no way to export vector artwork like this, as I have never managed to find an alternative that compares. I need to create some scaleable AW and nothing else works as well for drawing in vectors as Animate!

Any ideas how to get the swf export to work?

Would it work in the new version of Animate? I'm running a pretty old laptop and peripherals and don't want to update my operating system if I can avoid it (which I'd have to in order to run the new version)

Thanks!
