Solution 1Recommended

Convert Word 2016 Files to PDF Before Combining

Since Acrobat Pro X cannot directly process Word 2016 files, converting them individually to PDFs first bypasses the PDFMaker compatibility issue.

The Adobe PDFMaker plugin in Acrobat Pro 10 is not compatible with Office 2016. To get around this limitation, you must rely on standard PDF merging rather than direct Word-to-PDF combination.

1
Open your documents in Word 2016

Launch Microsoft Word 2016 and open the first document you wish to include in your combined PDF.

2
Save the document as a PDF

Click on 'File' in the top-left corner, select 'Save As', choose your destination folder, and select 'PDF' from the file format dropdown menu. Click 'Save'.

3
Repeat for all documents

Repeat the 'Save As' process for every Word 2016 document you want to merge.

4
Combine PDFs in Acrobat Pro X

Open Adobe Acrobat Pro X. Click on 'File', select 'Create', and choose 'Combine Files into a Single PDF'. Select all the newly created PDF files, arrange them in your desired order, and click 'Combine Files'.

Workaround Success: This method effectively bypasses the software limitation by using Acrobat Pro X only for what it still handles perfectly: merging standard PDF files.

Frequently Asked Questions

Why did Acrobat Pro X work with Word 2010 but not Word 2016?

Adobe PDFMaker in Acrobat Pro X was developed long before Word 2016 was released. The plugin does not support the newer architecture and lacks the necessary updates to communicate with Office 2016 applications.

Can I install an update for Acrobat Pro X to fix this compatibility issue?

No. Adobe Acrobat Pro X has reached its end of support lifecycle, meaning Adobe is no longer releasing new compatibility updates, bug fixes, or patches for newer Microsoft Office versions.

Is there a free way to combine Word 2016 documents into a PDF?

Yes. You can use the built-in 'Save As PDF' feature in Microsoft Word to export each document individually. Afterward, you can use a free office suite like WPS Office or a secure online PDF merger tool to combine the resulting PDFs.
