Fix Acrobat Pro 2020 License Expired Error When Printing to PDF
Question details
Users encounter a false 'license expired' or 'not activated' error prompt when attempting to use the Adobe PDF virtual printer from external apps, despite the software being activated.
- Product
- Adobe Acrobat Pro 2020
- Device & OS
- Windows
- Scenario
- Trying to print documents to PDF using the Adobe PDF printer from third-party applications like Microsoft Word or Google Chrome.
- Observed behavior
- The print job halts and displays an error claiming the Adobe Acrobat license has expired or has not been activated, even though the application can successfully create PDFs internally.
Ensure you have your Adobe Acrobat Pro 2020 activation details or account login handy. Save any unsaved work in Word, Chrome, or other external applications before restarting background services.
Restart the AcroTray Background Process
Restarting the AcroTray helper process is the fastest way to resolve communication glitches between external apps and the Acrobat licensing service.
The AcroTray.exe process runs in the background to handle the conversion workflow when printing to PDF from external applications. If it gets stuck or loses sync with your license, restarting it can clear the error.
Press Ctrl + Shift + Esc on your keyboard to open the Windows Task Manager.
Navigate to the 'Processes' or 'Details' tab and look for 'AcroTray.exe' in the list of running tasks.
Right-click on the AcroTray.exe process and select 'End task'.
Return to your external application (like Word or Chrome) and attempt to Print to PDF again. This will automatically trigger a fresh instance of AcroTray.
Temporarily Disable Security Software and Repair Acrobat
Antivirus or endpoint security software can block Acrobat's background licensing check during the print process.
Reinstall the Adobe PDF Virtual Printer
If the virtual printer integration is corrupted, removing and reinstalling it can restore standard functionality.
Create PDFs Effortlessly with WPS Office
Avoid frustrating virtual printer errors and licensing glitches entirely. WPS Office features a native, built-in PDF converter that lets you save any document as a high-quality PDF directly from the menu, without relying on external Adobe services or background processes.
- 1. Open Your Document: Launch WPS Office and open the Word, Excel, or PowerPoint document you want to convert.
- 2. Access the Export Tool: Click the 'Menu' button in the top left corner, or go directly to the 'Tools' tab.
- 3. Export to PDF: Select 'Export to PDF'. Configure your saving preferences, then click 'Export' to generate your PDF instantly.
Frequently Asked Questions
Why does Acrobat say my license is expired when it is clearly activated?
This usually happens because the background process (AcroTray.exe) that handles print jobs from external apps loses synchronization with Acrobat's main licensing module, or because third-party security software blocks the background validation check.
What is AcroTray.exe and do I need it running?
AcroTray.exe is an essential Adobe background process that facilitates the 'Print to PDF' workflow. If you disable it permanently, the Adobe PDF virtual printer will stop working. However, restarting it via Task Manager can fix temporary conversion errors.
Can I save as PDF in Chrome without using the Adobe virtual printer?
Yes. Google Chrome has its own built-in PDF generator. Press Ctrl + P to open the print dialog, and instead of choosing 'Adobe PDF', click the destination dropdown and select 'Save as PDF' to bypass Acrobat entirely.
