Flash CS4 contains all the standard documentation. It simply uses online documents by default when you have a network connection. Offline documents are stored at:
- WIN: C: \ Program Files \ Common Files \ Adobe \ Help \ en_US \ Flash
- OSX: / Library / Application Support / Adobe / Help / en _US /
By the way, to force the IDE to open offline documents automatically, open: Window > Extensions > Connections in the top menu. In the panel that appears, select the menu (upper right corner of the panel) and select "Offline settings" and check the box "Keep me offline."
