I heard theres a free download of LiveCycle Data Services ES. What is it?
Adobe offers two options to get you started with LiveCycle Data Services ES. You may choose to download, free of charge, the single-CPU license for production use. There is also a trial developer license for evaluation purposes that can be used for unlimited development on multiple CPUs. If you need support and a license to use on a multiple-CPU basis or you want to put your application into full-scale production, purchase LiveCycle Data Services ES with the appropriate user-level license and the optional Platinum Maintenance and Support.
