I cant find any trial versions of LiveCycle, is it somewhere hidden or it is all composed into new products, where it always directs me when I look for it? I need to test LC Designer or it's equivalent.
To get the Trial Designer ES4 try:
LiveCycle Blog: Designer ES4 direkte Download-Links//Designer ES4 direct download links
Otherwise download the trial of the AEM Forms Designer:
LiveCycle Blog: AEM Forms Designer Demoversion//AEM Forms Designer Trial
Looks like you might have to contact Adobe LiveCycle Trial Download
