- Product
- Adobe Acrobat XI Pro, Microsoft Word
- Device & OS
- not provided
- Scenario
- Attempting to export, save as, or print a Microsoft Word document as a PDF using the Acrobat PDFMaker add-in or the Adobe PDF printer.

Ensure you have your original Adobe Acrobat XI Pro serial number available, and verify that your Microsoft Word application is fully updated to minimize software compatibility conflicts.
Verify Activation and Repair Acrobat PDFMaker Add-in
This solution restores the communication between Microsoft Word and Adobe Acrobat by fixing missing configurations and confirming your license.
Often, Word updates or system changes can disconnect the PDFMaker add-in, prompting Acrobat to fail its activation check.
Open the Adobe Acrobat XI Pro standalone application. Go to the Help menu and ensure the software is activated. If prompted, enter your valid serial number here first.
Within Acrobat XI Pro, navigate to Help > Repair Acrobat Installation. Allow the automated process to complete, then restart your computer.
Open Microsoft Word, go to File > Options > Add-ins. Select 'COM Add-ins' from the Manage dropdown at the bottom and click Go. Ensure that the 'Acrobat PDFMaker Office COM Addin' box is checked.
Open your Windows Settings, navigate to Devices > Printers & scanners, and verify that 'Adobe PDF' is listed. If it is missing, you may need to completely reinstall Acrobat XI Pro.
Contact Adobe Support for Legacy Activation
Use this step if your serial number is valid but continues to be rejected by the Acrobat XI Pro software.

Frequently Asked Questions
Why does Acrobat XI Pro suddenly ask for a serial number?
This usually happens if the activation token gets corrupted, the Adobe PDF printer driver malfunctions, or an Office update disrupts the connection with the Acrobat PDFMaker add-in.
Does Adobe still provide updates for Acrobat XI Pro?
No, Adobe officially ended support for Acrobat XI Pro in October 2017. While the software can still run, bug fixes, security patches, and activation server reliability are no longer maintained.
Can I create a PDF in Word without Adobe Acrobat?
Yes. You can use Microsoft Word's native 'Save As' feature and select PDF as the format, or use alternative productivity suites like WPS Office which feature robust, built-in PDF export tools.
What should I do if my valid serial number is rejected?
If your serial number is rejected despite being valid, it is likely due to the retirement of older Adobe activation servers. You will need to contact Adobe support directly to request an activation override or licensing assistance.
