If you don't see any LightScribe-related stuff in Acoustica CD/DVD Label Maker (such as a "LightScribe" button on the main toolbar or a "LightScribe" page on the Preferences dialog), it probably means you haven't installed the LightScribe System Software.
HP no longer provides the software at lightscribe.com or any of it's other websites.
You can download the LightScribe System Software here.
There are a couple other LightScribe software prerequisites as well: you need to be running Windows 2000, XP, Vista, 7 or 8 and you also need to be running version 3 or higher of Acoustica CD/DVD Label Maker for LightScribe to work.
