In which way Actionscript 3 reference can be downloaded?

I have used F开发者_运维问答lash Builder 4 built-in help viewer, and I'm pretty sure there was an option to download the reference. But I have once selected "view help in browser", and from then I can't see an option to come back and use the help viewer as before, and thus I can't find the reference download option.

btw, the reference is available online at:

http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/index.html

Thanks in advance

Run the Adobe Help application, go into preferences, select General Settings, and change the preference from "Open Help in Browser" to "Open Community Help Application". Hope that helps.
