Acrobat fails to access the OCR service on Windows

Problem: Acrobat fails to access the OCR service

Applicable to Windows

When you attempt to apply Optical Character Recognition (OCR) on a scanned page or an image, Acrobat may fail to access the OCR service due to low system memory, incomplete/corrupted files, unsupported formats, outdated software, or inadequate resources. Acrobat displays the following error: "Acrobat could not access the recognition service because: Unable to locate the paper capture recognition service."

Error message - could not access the recognition service


To fix the error, try the following solutions in the order they appear below.

Solution 1: Copy the files from the 'iDRS15' folder to the 'PaperCapture' and 'plug_ins' folders in Acrobat

  1. Go to the location:

    C:\Program Files\Adobe\<Acrobat Version>\Acrobat\plug_ins\PaperCapture\iDRS15

    For example, for Acrobat, go to:

    C:\Program Files\Adobe\Acrobat\Acrobat\plug_ins\PaperCapture\iDRS15

  2. Copy all the files in the folder.

  3. Go to the following locations and paste the copied files:

    • C:\Program Files\Adobe\<Acrobat Version>\Acrobat\plug_ins\PaperCapture
    • C:\Program Files\Adobe\<Acrobat Version>\Acrobat\plug_ins

Try running OCR using the Scan & OCR tool in Acrobat.


If Acrobat crashes during OCR even after following the above steps, delete the old files from the folders specified in Step 3. If the crash stops but the OCR issue remains, repeat the steps in solution 1.

Solution 2: Uninstall and reinstall Acrobat
