System requirements

ActionScript 2.0 does not have any system requirements in addition to Flash 8.
This manual assumes that you are using the default publishing settings for your Flash files:
Flash Player 8 and ActionScript 2.0. If you change either of these settings, explanations and
code samples in the documentation might not work correctly. If you develop applications for
earlier versions of Flash Player, see
Player," on page 787.

Updating Flash XML files

It is important that you always have the latest Flash XML files installed. Macromedia
sometimes introduces features in dot releases (minor releases) of Flash Player. When such a
release is available, you should update your version of Flash to get the latest XML files.
Otherwise, the Flash 8 compiler might generate errors if you use new properties or methods
that were unavailable in the version of Flash Player that came with your Flash installation.
For example, Flash Player 7 (7.0.19.0) contained a new method for the System object,
System.security.loadPolicyFile
Updater installer to update all the Flash players that are installed with Flash. Otherwise, the
Flash compiler displays errors.
Remember that you can install a Player Updater that is one or more major versions ahead of
your version of Flash. By doing this, you will get the XML files that you need but shouldn't
have any compiler errors when you publish to older versions of Flash Player. Sometimes new
methods or properties are available to older versions, and having the latest XML files
minimizes the compiler errors you get when you try to access older methods or properties.
