MacDraw Pro: Can‘t Install by Clicking On Installer Script

This information was provided by Claris Corporation on 16 March 1998, and incorporated into Apple Computer's Tech Info Library.
This is fixed in MacDraw Pro 1.5

Double-clicking on the Installer Script file will NOT launch the Installer program, even though they both have the same creator type. The solution is to double-click on the Installer application. The installation instructions for MacDraw Pro state that you must click on the Installer file, not the Installer Script file.
