Group Policy Installation
From Audacity Wiki
has written a .VBS script that will automatically install Audacity via Group Policy to computers on a network. Group Policy is available on computers running Windows 2000 or later. The script and thorough instructions as an HTML document and a quick start text document are available . The script will only install Audacity if its installation folder is not already present in Program Files (or the directory of your choice), and will also install Start Menu and desktop shortcuts for all users (if you so choose).
