How to purchase AEM Forms Designer

You can't technically buy LiveCycle anymore as it was decommisioned back in 2018 or so. What you can do is buy Adobe Experience Manager Designer. This is essenitally that same desktop application you were using so you can still load your forms into it and have the same functionaility as before.

Take a look at this FAQ if you are looking at more details comparing the legacy LiveCycle solution to the modern Designer tool.

If you have AEM Forms license Adobe will provide you with a copy. Send email to spphelp@adobe.com and ask for download links, they should be able to help.

Another option for forms design:

Adobe InDesign versions CC:2018 (13.1 in March 2018) or the current CC:2019.

I've designed forms for eons and teach classes in the topic. Forms from InDesign is the best and easiest method. Doesn't give you all the tools for scripting, calculations, etc., but basic form creation is solid and accessible — the rest can be added in Acrobat.

I have a class in accessible PDF forms from InDesign. It's being updated and will be offered again after the new year. Will have 2 versions of the class: Accessible PDF Forms from InDesign, and Accessible PDF Forms from Word and Acrobat. https://www.pubcom.com/classes/508-classes.shtml#forms508

No, Adobe no longer sells the stand-alone LiveCycle Designer. If you can get your hands on a legit copy, you can still run it on current Windows 10 workstations.

If you have older versions of Acrobat Pro, look through your CDs or installation files for versions of Acrobat X or CS 4, and install "Designer" from them.

I saw a reply suggesting you could no longer buy Designer, only the whole of AEM. But info Is scarce.

I think it's best to think of AEM Forms as a subscription cloud-based service, rather than an individual software program that you can buy and install on your computer.
