Repair and Update Adobe Acrobat Installation
Use this solution to fix corrupted or missing PDFMaker add-in files by repairing the current installation and applying the latest software patches.
Software corruption or outdated application versions frequently cause missing resource files. Running the built-in repair tool can restore the missing PDF Maker components necessary for portfolio creation.
Open Adobe Acrobat Pro 2017, navigate to the 'Help' menu at the top, and select 'Repair Installation'. Allow the process to complete and restart your computer.
Relaunch Acrobat, go back to the 'Help' menu, and click 'Check for Updates'. Download and install the latest available release for your installed product.

Pre-convert Unsupported Attachments
Apply this method if the error is triggered by specific files or unsupported attachments failing to convert during the automatic portfolio creation.
Review Acrobat PDF Preferences
If the missing PDF Maker files message appears only as a warning but does not stop the portfolio generation, adjusting your preferences may suppress the alert.
Combine Files Smoothly with WPS Office PDF
Avoid PDF Maker missing file errors entirely by using the WPS Office PDF toolkit to easily merge multiple files, documents, and attachments into a single, comprehensive PDF document.
- 1. Launch WPS PDF: Open WPS Office on your computer and navigate to the PDF tab.
- 2. Select Merge PDF: Click on the 'Merge PDF' tool located in the main PDF toolbar or toolkit menu.
- 3. Add Your Files: Click 'Add Files' to import all the documents and attachments you wish to combine into a single file.
- 4. Merge and Save: Arrange the uploaded files in your preferred order, click 'Merge', and save the newly created, consolidated PDF document to your device.

Frequently Asked Questions
Why does Acrobat say 'Unable to find Adobe PDF resource files'?
This error typically occurs when the Adobe PDFMaker add-in is corrupted, outdated, or when Acrobat is attempting to batch-convert an unsupported file format during the portfolio creation process.
How do I fix unsupported attachment errors in a PDF Portfolio?
The most reliable method is to individually convert the problematic attachments into standard PDF format using their native applications (such as Microsoft Word or WPS Office) before adding them to your final portfolio.
Can I combine files into a PDF without using Adobe Acrobat?
Yes, you can use alternative solutions like the WPS Office PDF toolkit. The 'Merge PDF' feature allows you to seamlessly combine multiple documents and image files into one PDF without relying on Adobe's PDF Maker.
What should I do if the Acrobat repair tool fails to fix the issue?
If repairing the installation from the Help menu does not resolve the missing PDF Maker files, you may need to perform a complete uninstall of Adobe Acrobat Pro 2017, restart your computer, and reinstall the software fresh.
