Frequently Asked Questions

Why does telephone activation for Acrobat 8 no longer work?

Adobe has permanently decommissioned the activation servers and removed telephone support for older legacy products like Acrobat 8, making it impossible to activate them via traditional methods.

Can I use Adobe Acrobat Pro DC to edit LiveCycle Designer forms?

No, Adobe Acrobat Pro DC cannot directly replace LiveCycle Designer for editing existing dynamic LiveCycle (XFA) forms. You must use AEM Forms Designer, which is the current successor to LiveCycle Designer.

What is the new name for Adobe LiveCycle Designer?

Adobe LiveCycle Designer has been rebranded and integrated into Adobe's modern enterprise solutions. It is currently known as AEM (Adobe Experience Manager) Forms Designer.

How do I open dynamic LiveCycle forms if I don't have the designer?

To simply view or fill out dynamic XFA forms, you typically need to use a properly configured version of Adobe Acrobat Reader. Standard browser-based PDF readers will usually display a 'Please wait' error message.
