Yes, you have to Reader-enable the document. In Acrobat, select: Advanced > Extend Features in Adobe Reader
Thank you. This works.

Thanks to all for the suggestions.
Enabling the signatures was successful but now we've found that using the Adobe LiveCycle form isn't as intuitive for our users as a simple Word template. Is there a simple way to fill out a form in Word and export it to PDF to manage the signatures? Word is great for filling out the form but it's signature functions are lacking. Our form needs to be completed by a manager, locked down except for a comments field. The comments field is to be locked after the first signature. The document then needs an additional three successive signatures.
Ideally, we would like to fill the form out in Word and then let Adobe take care of the signature processes.
