Publishing SWF that uses Flex SDK

When i test the flash application from inside the flas开发者_JAVA技巧h-cs4 it works fine, but when i try to export the movie, it gives an error:

You have used a feature that requires the Flex SDK: Embed metadata Please set the Flex SDK path if necessary and add it to the library path for this file. The Flex SDK folder contains the bin, frameworks, lib and other folders.

I check on the settings and in the library path i have an entry: ${FlexSDK}/frameworks/libs/flex.swf. What else do i have to do to make the exported swf work?

ps: I use the Embed meta-tag in my app.

target the Flex .swc file. path example:

SDKs/flex_sdk/4.1.0/frameworks/libs/flex.swc
