You must purchase Embird basic for the iconizer to work.

I have basic Embird and its Iconizer plug-in. I do not know how I ever did machine embroidery without them! Basic Embird has so many great features alone, but then you can purchase the Iconizer, or other plug-ins, as needed/wanted. As stated by Pcteddyb, you do have to purchase the basic, before you can buy the plug-ins. The absolute best software for the price, to assist with this craft! I cannot rave too highly on the Iconizer. It opened up a new world in allowing one to view full color designs within folders, rather than just format icons!! Love it!
