The maintenance period of Adobe LiveCycle Designer ES4 ends with Mar 2018 and extended support ends in 2020. Can you please let me know the replacement product for Adobe LiveCycle Designer ES4. I am referring only to the core designer functionality to be able to create/edit forms in a desktop, and not any advanced features.
The Adobe LiveCycle Designer has been renamed to AEM Forms Designer, principally the same tool but in a newer version. If you need to update it depends on how you purchased the Designer and if you are eligible for an Update.
