The most up to date version of ACT is always available from the ACT web pages.
Before installing ACT you will need to make sure you have Java installed.
Linux, UNIX users should get the current Java version from the Oracle.
Windows users should get latest stable release from Java version from Oracle. On some versions of Windows (such as Windows 2000) you will need be have administrator privileges for your machine to successfully install Java.
Macintosh users with MacOS X should have Java installed. You can get the latest Java 1.6 version from Apple. Java 7 for Intel Mac running Mac OSX 10.7.3 or above can be downloaded from Oracle.
Change directory to the directory you wish to install ACT in. We will use ~/ in this example and in the next chapter. Uncompress and untar the act_compiled.tar.gz file. The command is:
tar zxf act_compiled.tar.gz
This will create a directory called ~/act which will contain all the files necessity for running ACT.
For instructions on how to run ACT on UNIX and GNU/Linux once the archive is unpacked see the section called Running ACT on UNIX and GNU/Linux Systems in Chapter 2.
For MacOSX users an archive artemis_act.dmg.gz disk image is provided. This contains both Artemis and ACT applications. This can be uncompressed using gunzip:
gunzip artemis_act.dmg.gz
Alternatively on OS X an easier solution is provided by StuffIt Expander. Double-click on any file ending in ".gz" and StuffIt Expander will be launched to uncompress that file.
On Windows systems with Java (version 1.6 or higher), installing ACT is as simple as downloading the the act.jar file to an appropriate place (such as the desktop or the Programs folder). When downloading some versions of windows mistake this file for a zip file ensure it does not name this act.zip, if it does rename it to act.jar (DO NOT UNZIP THIS FILE).
