You can always download the most recent installation files for your Embrilliance Embroidery software. Embrilliance offers a consistently updated downloads page that contains the installation files for both Mac and Windows operating systems.
Which installer do I need for my Embrilliance program?
If you are installing Essentials, AlphaTricks, Enthusiast, Density Repair Kit, either of the Font Collections, or StitchArtist, you need the Embrilliance Platform installer for Mac or Windows, depending on your computer. All of the programs above run in a single window and are installed using the same installation file, and the programs are enabled by adding the serial number from each program to the platform.
If you are installing Thumbnailer or the Accuquilt libraries, you'll find the installation files for those at the bottom of the downloads page.
