If you are using a version of Mac OS earlier than 10.2, you’ll need to use version 1.2.3. (NOTE: Addressix is supported only for Mac OS X, and does not run under 10.7 “Lion”.)

Addressix is distributed as a disk image. If it doesn’t open automatically, double-click the .dmg file. Then drag the Addressix application icon to where you’d like to install it.

If you’ve registered an earlier version of Addressix, the new version will recognize your registration.
