Frequently Asked Questions

Why does Adobe Acrobat say my license has expired when I have an active subscription?

This commonly happens due to synchronization issues between your local software and Adobe's activation servers, especially after a recent software update or if your system's date and time settings are incorrect. Updating the app and logging out and back in usually resolves it.

How do I check my current Adobe Acrobat version?

Open Adobe Acrobat, navigate to the 'Help' menu at the top, and click on 'About Acrobat'. A dialog box will appear displaying your exact build and version number.

Can I still view PDFs if my Adobe Acrobat license is expired?

If your Acrobat Pro or Standard license expires, the application may block access or revert to basic reader mode depending on your exact installation. If you are entirely locked out, you can use a free alternative like WPS Office or Adobe Acrobat Reader to view your files.
