Question details
The user needs to resolve an error preventing the Acrobat DC Modify or Edit tool from opening.
- Product
- Adobe Acrobat DC
- Device & OS
- not provided
- Scenario
- Attempting to edit or modify a PDF document using the built-in tools in Acrobat DC.
- Observed behavior
- An error referencing OCRLibraryInf.dll and the setDeskew entry point appears, blocking the Modify or Edit tool from launching.
Ensure you have administrative privileges on your computer and close Adobe Acrobat completely before modifying files in the installation directory.
Copy Missing OCR Files from the iDRS15 Folder
Manually replace the mismatched OCR component files within the Acrobat directory to restore the Modify and Edit tool functions.
This error generally occurs when Adobe Acrobat's internal OCR component files become mismatched or corrupted. Copying the correct files from the localized iDRS15 folder into the active plugin directories manually forces Acrobat to use the proper recognition service files.
Ensure that Adobe Acrobat DC is completely closed and not running in the background.
Open File Explorer and navigate to your Acrobat installation path, typically located at C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\.
Find and open the folder named 'iDRS15'. Select all the files inside this folder and copy them.
Navigate back to the main Acrobat directory. Paste the copied files into the 'PaperCapture' folder. Then, paste the same files into the 'plug_ins' folder.
Launch Adobe Acrobat DC again, open a PDF document, and click on the Edit or Modify tool to verify that the error is resolved.
