This article describes how AppleWorks 6 is installed in Mac OS 9.1 and Mac OS X when updating from AppleWorks 6.0.4 to AppleWorks 6.1.2

With the North American English version of AppleWorks 6.0.4 and Mac OS 9.1 or Mac OS X installed, the AppleWorks 6.1.2 Updater replaces the AppleWorks 6.0.4 application with an application package that contains both AppleWorks 6.1.2 for Mac OS 9.1 and AppleWorks 6.1 Public Preview for Mac OS X.

An application package is not a single executable file, but a package of files that includes one or more executable binaries. In this case, the package contains two binaries. One for Mac OS 9.1, and one for Mac OS X.

Mac OS 9.1 Installation

When you start up a computer with Mac OS 9.1, and double-click on the AppleWorks 6.app file, AppleWorks 6.1 for Mac OS 9.1 opens.

Mac OS X Installation

When you start up a computer with Mac OS X, and double-click on the AppleWorks 6 file, the AppleWorks 6.1 Public Preview for Mac OS X opens.

Note: The ".app" extension is not visible in Mac OS X. The filename will appear as "AppleWorks 6" when in Mac OS X, and as "AppleWorks 6.app" when in Mac OS 9.1.
