I have a lot of forms that we have created over the years in LiveCycle/Adobe EM and I'm unable to edit them with the new Adobe Acrobat Pro. We had this functionality when we had Abobe 9 Pro. Why did Adobe screw up their own products with no integration between them?
Livecycle Designer was a seperate product. It was bundled with Acrobat Pro 9 and X.
It's just aggrevatring that Adobe's own product that came with Pro no longer works with Pro. It's going to take months to recreate these forms in a new product that's already a pain to figure out.
It was never possible to edit such forms in Acrobat. You had to have LCD (now AEM) to edit them, and that's still the case now.
You can edit this forms with the AEM Forms Designer.
Nothing has changed at all, except that LiveCycle Designer was once bundled with Acrobat Pro and now it isn't. There was never integration, except that a create form button in Acrobat used to run LiveCycle Designer. Like many things, this was to be the future, and now it wasn't. XFA forms like these are obsolete now.
