Okay, so every so often when I am editing a form ((MAINLY FORM 8821, from the IRS)) I get a message that my form cannot be edited in Adobe & that it needs to be edited in LiveCycle Designer... But where & How do I do this. I can't info on LiveCycle Designer anywhere! And so when I ask adobe for tech support I am told that adobe does not offer support for livecycle any longer!
Well with Acrobat XI they replaced LiveCycle with FormsCentral, which used LiveCycle internally but ultimately produced AcroForms. After XI, they removed a form generation product altogether in Acrobat, suggesting SMBs use a third party product, or look at AEM Forms. AFAIK, there are no drop in replacements for the creation of XFA forms outside of AEM Designer.
