This page includes the sentence, “Livecycle Designer ES2 is included with Acrobat Pro for Windows.” So far, I haven’t found it in my CS6 Master Collection, which includes Acrobat Pro. I did find the help file in the folder, Designer 9.0, but it doesn’t say where to find the program or how to launch it. So how do I access it?
There are two methods of getting to Designer (based on AA9 Pro on Win7). (1) Open Acrobat and select Forms>Start Form Wizard>Create a PDF form from Scratch. Designer should open and give you options on creating a PDF form. (2) In start menu, select Adobe>Adobe LiveCycle...
You do not have to use Designer to create forms. If you do, any PDF will no longer be available for editing in Acrobat, only Designer. You can load a PDF or select from the wizard to use a PDF and the form tools in Acrobat can be used. These tools create what is called an AcroForm rather than the LiveCycle form. There are some differences in the flexibility of the two form methods and it is probably best to try out both methods to form your own opinion. I grew up on AcroForms and have not used Designer much. One thing Designer does provide are dynamic forms that allow a field size to grow and such. However, that is an advanced aspect that is not needed for most folks.
Anyway, both AcroForms and Designer forms are available from Acrobat Pro. For Designer, it is ONLY available for the Windows platform, not a MAC. Since you did not indicate which you have, the MAC is a possiblity.
