Use of extended features is no longer available
I am trying to help someone else with a form fill problem. They downloaded a form and received the above message. So I downloaded the Form1040. When I tried to fill it out I received the following also:
This document enabled extended features in Adobe Acrobat Reader. The document has been changed since it was created and use of extended features is no longer available.
After selecting the OK button and even though the Fill sign option is present, once selected the cursor doesn't change and I am unable to fill in the form.
Then I looked on my drive and randomly picked pdf documents, opened them. First of all there was no error. Secondly even on those with no fill-in fields after selecting the Fill Sign option the cursor changed and I was able to write wherever I wanted on the forms. Full disclosure I did not create any of the pdf files. Some were books other forms. Can anyone help me? I feel like I'm on the hamster wheel
Title shortened by moderator for clarity. Was “This document enabled extended features in Adobe Acrobat Reader. The document has been changed since it was created and use of extended features is no longer available.”
