You might try updating Acrobat DC and see if that fixes the issue.
Launch Acrobat>navigate to Help menu>select Check for Updates.
Could you please let me the version of Acrobat DC installed on the machine?
To check the version of Acrobat, launch Acrobat>navigate to Help menu>select About Adobe Acrobat DC
Which operating system do you have- Windows/Mac?
Have you tried using Fill & Sign on other pdfs?
We have released an update in which this issue has been fixed, try to update Acrobat DC, restart the machine, and then try to use the Fill & Sign feature.
Launch Acrobat DC>navigate to Help menu>click on Check for updates
Let us know the results.
I just tried the 'Check for Updates' as advised and it says no updates available.
And it is still not working.
Any other thoughts?
Installed Adobe Acrobat DC Version 15.020.20039
Try to follow the below mention steps and see if it works:
1- Repair Acrobat installation, launch Acrobat DC>navigate to Help menu>select Repair installation (for Windows).
2- If that doesn't work, try removing Acrobat DC using Cleaner tool (for Windows) from here: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs , restart the computer, and reinstall Acrobat.
For Mac, uninstall Acrobat DC, visit this link for the same: How can I remove a program from my mac? |Official Apple Support Communities and reinstall.
Let me know if it worked.
I have already tried 'Repair' and Uninstalling and Reinstalling the software.
I am told this is an issue with a number of adobe customers and am yet to be advised on a solution (over 2 weeks later). Currently have a 'band aid' fix which makes the process twice as long.
This issue is highly effecting productivity in our business and i'm quite disappointed with the support and response received.
If this is not resolved soon I will be requesting a refund as the software is not functioning as promised.
