My team creates XFA forms in Forms Designer 6.2. When we add a digital certificate to the form [using Acrobt Pro 2017 > Tools Certificates > Certify (Invisible Signature)] and then extend it to have basic usage rights, the digital certificate invalidates or disappears.
We have a workaround for this where the form is first opened in LiveCycle ES3 and the target version is saved (through Form Properties) "8.1 or later". For some reason, this allows the certificate to be successfully added and maintain its validity.
We will be losing access to LiveCycle ES3 and will not be able to use this workaround. In Designer 6.2, we can only set the target version to "10.0 or later" and the certificate fails.
Does anyone know how to solve this issue? Alternatively, is there a workaround to save files as 8.1 without using ES3?
