How to Fix Acrobat 9 OCR Error: Source Files Cannot Be Found
Question details
The user needs to resolve an issue in Acrobat 9 Pro where an OCR sequence fails to execute due to a missing source files error.
- Product
- Adobe Acrobat 9 Pro
- Device & OS
- not provided
- Scenario
- Attempting to run an Optical Character Recognition (OCR) sequence on a PDF document to extract or recognize text.
- Observed behavior
- The application displays an error message stating that the OCR sequence cannot run because one or more source files cannot be found.
Ensure that the PDF file you are trying to OCR is saved locally on your computer's hard drive (e.g., the Desktop) rather than on a network drive or external USB, as connection drops can trigger file access errors.
Install Pending Acrobat 9 Updates
Installing the latest available patches for Acrobat 9 may resolve underlying software bugs that cause the OCR process to lose track of source files.
Although Acrobat 9 is officially unsupported, applying the final updates released by Adobe for this version can sometimes patch critical processing bugs.
Launch Adobe Acrobat 9 Pro, navigate to the top menu bar, and click on 'Help'.
Select 'Check for Updates' from the dropdown menu to allow the application to search for available patches.
Follow the on-screen prompts to download and install any pending updates. Once the installation is complete, restart your computer and try running the OCR sequence again.
Upgrade to a Modern PDF OCR Application
Because Acrobat 9 is obsolete and incompatible with modern operating systems, switching to a currently supported PDF application is the most reliable solution.
Use WPS Office for Reliable PDF OCR
Avoid the compatibility issues of obsolete software. WPS Office provides a powerful, built-in OCR tool to easily extract text from scanned PDFs and images, fully compatible with all standard PDF formats.
- 1. Open the PDF in WPS Office: Launch WPS Office and open the scanned PDF document you want to process.
- 2. Access the OCR Tool: Navigate to the 'Tools' tab on the top ribbon and click on the 'OCR' button.
- 3. Select Output Format: Choose whether you want to extract the text directly, or convert the scanned PDF into an editable Word document.
- 4. Process and Save: Click 'Start' to allow WPS Office to recognize the text. Once finished, save your new editable document.
Frequently Asked Questions
Why does Acrobat 9 say source files cannot be found during OCR?
This error usually occurs if the file path is too long, the PDF is located on a disconnected network drive, or the outdated OCR engine in Acrobat 9 encounters a compatibility bug with your current operating system.
Is Adobe Acrobat 9 still supported?
No, Adobe Acrobat 9 has reached its end of life. Adobe no longer provides technical support, security updates, or bug fixes for this version, making it prone to errors on modern computers.
Can I fix the Acrobat OCR error without upgrading?
You can try moving the PDF to your local desktop, shortening the file name, or installing the final updates released for Acrobat 9. However, if these steps fail, upgrading to a supported PDF editor is the only permanent fix.
What is a good alternative for performing OCR on PDFs?
WPS Office is an excellent modern alternative that features a built-in OCR tool. It allows you to extract text from images and scanned PDFs quickly and accurately, bypassing the bugs found in outdated software.
