Solution 1Recommended

Verify Version Compatibility and Repair Microsoft Office

Acrobat relies on a functioning Microsoft Office installation to process DOCX files. Verifying version compatibility and repairing Office often resolves recognition errors.

Adobe Acrobat uses background integration with Microsoft Word to convert DOCX files. If Word is damaged, not installed, or incompatible with your version of Acrobat, the file will not be recognized.

1
Check version compatibility

Open Adobe Acrobat and navigate to Help > About Adobe Acrobat to check your version. Do the same in Microsoft Word under File > Help. Verify on Adobe's official support site that your version of Acrobat supports your installed version of Microsoft Office.

2
Open Windows Control Panel

Click the Windows Start menu and select 'Control Panel'. Click on 'Programs' or 'Programs and Features' to view your installed software.

3
Repair Microsoft Office

Locate Microsoft Office in the list of installed programs, right-click it, and select 'Change'. Choose 'Quick Repair' or 'Repair' and follow the on-screen prompts to fix any corrupted integration files.

Do I need Microsoft Word installed to convert a DOCX file in Acrobat?

Yes, standard desktop versions of Adobe Acrobat require a working installation of Microsoft Word to render the text and convert DOCX files into PDFs effectively.

How do I fix a disabled Acrobat PDFMaker add-in in Word?

Open Microsoft Word, navigate to File > Options > Add-ins. From the 'Manage' dropdown at the bottom, select 'COM Add-ins' and click 'Go'. Finally, ensure the box for the 'Acrobat PDFMaker Office COM Addin' is checked and click OK.
