I have been using this program with no issues until this week where the save icon is not highlighted and save as does not respond.
How do I fix this issue so I can save my documents?
Please try to repair the installation.
Go to Help Menu > Repair installation and then relaunch the application.
Could you please confirm the dot version of Adobe application you are using.
Do you experience this issue with the all the PDFs you work on or on some particular file?
Are you on Mac or on Windows? OS version?
That worked thank you.
It was happening with every PDF.
I am on Windows 10.
Glad to know that it worked for you.
Let us know if you need any assistance in future.
