How can build for holder version of Flash Player

[Taorepoara]

Hi, I would like to build a project that can be played in old version of Flash Player (like 10.2) and to use new components (like Worker or Stage3D that are anebled since version 11.?) only only if the Flash Player version permit it.

I use Flash Builder.

Thanks

After many test I finaly resolved my problème

You just have to build using the SDK version and uncheck the check of the Player version in the template management.

Sorry for your time
