Ensure you have administrative privileges on your Windows computer, as you will need to test a new user profile or perform a clean reinstallation of the software.
Test Acrobat Under a New Windows Administrator Profile
Creating a new administrator profile helps determine if the OCR error is being caused by corrupted user profile permissions or settings.
Sometimes, system-level file access issues are tied to a specific user account. Testing the application on a fresh Windows profile can bypass these hidden permission blocks.
Press the Windows key + I to open Settings, then navigate to 'Accounts' and select 'Family & other users'.
Click 'Add someone else to this PC', follow the prompts to create a local account, and set the account type to 'Administrator'.
Log out of your current Windows session and log back in using the newly created Administrator profile.
Launch Adobe Acrobat DC, open a scanned document, and run the Scan & OCR tool to see if the entry point error still appears.
Clean Reinstall Acrobat Using the Cleaner Tool
If testing a new profile fails, performing a clean uninstallation replaces missing or corrupted OCR library DLL files entirely.
Use WPS PDF to Extract Text from Scanned Documents

Frequently Asked Questions
What exactly is the OCRLibraryInf.dll file?
OCRLibraryInf.dll is a dynamic link library file used by Adobe Acrobat DC to execute optical character recognition (OCR) functions. When this file is corrupted, missing, or blocked by system permissions, the software cannot process scanned images into text.
Can I fix the error by downloading a new OCRLibraryInf.dll file from the internet?
It is highly discouraged. Downloading individual DLL files from third-party websites can introduce malware to your system and often results in version mismatch errors. Reinstalling the software is the only secure method.
Will using the Acrobat Cleaner Tool delete my personal PDF files?
No. The Acrobat Cleaner Tool only targets the application's installation files, preferences, and residual registry keys. Your saved personal PDF documents will remain safe on your hard drive.
