Reader Extensions is a service of Adobe Experience Manager Forms (previously known as LiveCycle Reader Extensions) that is used to extend the functionality of Adobe Reader with additional usage rights. The service adds usage rights to a PDF document and activates features that are not usually available when a PDF document is opened using Adobe Acrobat Reader DC, such as adding comments to a document, filling forms, and saving the document.

When a PDF is Reader Extended, a digital certificate/credential allows users to interact with a PDF in the free Acrobat Adobe Reader DC as if they have a copy of Acrobat Professional DC. This allows users to perform operations like saving the data entered into a fillable PDF form.

This certificate/credential has an expiry date of January 7, 2023. When a user attempts to open a PDF with an expired certificate/credential, they will receive the following error:

The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document.

The PDF will still open but any extended rights added to the document will no longer work.

To ensure your PDFs continue to work past the expiry date, the following steps need to be taken:

1. Obtain a new certificate/credential from Adobe with a new expiry date of 2035

2. Remove the rights from PDFs with extended rights

3. Re-extend the PDFs with the new certificate/credential
