How to Fix the 'Missing PDFMaker Files' Error When Combining PowerPoint Presentations

Product: Adobe Acrobat Pro, Microsoft PowerPoint
Device & OS: not provided
Scenario: Combining multiple PowerPoint presentations into one PDF document directly through Adobe Acrobat.
Observed behavior: A 'Missing PDFMaker Files' error prevents the files from merging, even though exporting the individual PowerPoint presentations to PDF natively works without issue.

Before you start

Ensure you have saved all open PowerPoint presentations and check that neither Microsoft Office nor Adobe Acrobat Pro are running background tasks before attempting to repair the software.

Solution 1Recommended

Repair Adobe Acrobat and Install Updates

Running the built-in repair utility can fix corrupted or missing PDFMaker add-in files causing the combination error.

The PDFMaker add-in acts as a bridge between Adobe Acrobat and Microsoft Office. When its files become corrupted or incompatible due to out-of-sync software versions, Acrobat cannot process the PowerPoint files directly for merging.

Run the Repair Utility

Open Adobe Acrobat Pro. Navigate to the 'Help' menu at the top of the application window and select 'Repair Installation' (or 'Repair Acrobat Installation'). Follow the on-screen prompts to complete the process.

Check for Acrobat Updates

Once the repair is finished, go back to the 'Help' menu and click 'Check for Updates' to ensure you are running the latest version of Adobe Acrobat.

Update Microsoft Office

Open Microsoft PowerPoint, go to 'File' > 'Account' (or 'Office Account'), click on 'Update Options', and select 'Update Now'.

Restart and Test

Restart your computer to apply all changes, then open Adobe Acrobat and attempt to combine the PowerPoint files again.

Repair Adobe Acrobat and Install Updates

Verify Compatibility: Older versions of Adobe Acrobat may not support the PDFMaker add-in for the newest versions of Microsoft Office. Ensure both applications are within their supported lifecycles.

Open PowerPoint and go to 'File' > 'Options' > 'Add-ins'. In the 'Manage' dropdown menu at the bottom, select 'COM Add-ins' and click 'Go'. Ensure that the box next to 'Acrobat PDFMaker Office COM Addin' is checked.
