Nothing revolutionary today, folks, on account of the ridiculous amount of time I spent today trying to get Flex 3 to compile Flash 10 SWFs. I had to use a combination of information from several sources, including the below:

Flash 10 / Astro Installation Guides

It would be pointless for me to go through it again, since I think they’ve pretty much got it covered. However, there are a couple valuable things I learned:

Setup Tips

1- I couldn’t get things to work with the last “stable” build (May 16- v3.0.1.1732), so my advice would be to go with one of the more recent ones. I’m using v3.0.1.1954, myself.

2- There is in fact a debug player, and it is here. I’m not sure why this isn’t mentioned in the documentation.

3- The debug player is standalone, so you won’t be able to debug in your browser. Instead, in your launch configuration (Project > Properties > Run/Debug Settings > New (or Edit)), point the Debug URL to the actual SWF you’re producing, not the generated HTML page. Then you can tell your OS to run SWFs with the standalone debug player, and then you’ll be able to actually see what you’re doing.

4- From my experience, I estimate that actually reading Adobe’s instructions before trying this will save you approximately four and a half hours.
