the autoplay feature is already part of blindwrite and installed. It has been since 4.2.7. The autoplay feature is a free stand alone that enables you to play (emulate) your copy on another computer without installing the complete blindwrite program. You do not burn it to the cd but install it on another computer where blindwrite is not installed. The license you purchase for blindwrite is good for one computer, but in order to play your copy in another computer where blidwrite is not installed you only need to install the autoplay filter.
