If you’re like me right now dealing with this problem. you might take a look bellow to to fix this annoying problem. Specially if you’re running Flash 10.0.2.
When you upgrade to Flash IDE 10.0.2 the Adobe Flash Team has a bug that doesn’t really shows even on Bugbase I searched there and found nothing.
How to fix that?
1. Open up Flash IDE CS4
2. Go to menu Help > Manage Extension
3. Search for the Flash Component Kit CS3.mxp instalation file, even if you’re going to look at CS4 will not find, but it works with CS4 version.
4. Install and activate.
But if you already installed the FCK and didn’t workout do the same as steps above except number 4. To work just mark the installed FCK.
Simple as that, It toked me an our to figure out that.
