I have created a form using LiveCycle Designer and sent to users to fill it out, The users who are using Adobe Reader and Adobe Acrobat Pro can fill the form but users who are not using Adobe Reader and Adobe Acrobat Pro (they are using other PDF applications such as Nitro, Nuance, etc.) unable to fill the form, Please advise that why LiveCycle forms not opening/supporting in other PDF applications, or is there way to sort it out this issue? Note: I am using LiveCycle Designer ES4 version.
It's up the other PDF application produces to decide how much of the functionality of Reader that they support. In my experience there seems to be better support for static forms, but becomes a nightmare like having to test the form in all the applications, like testing a web page in all browsers I guess.
