Problem: Could not access the recognition service

When you attempt to apply optical character recognition (OCR) to a file, you receive the error message, "Acrobat could not access the recognition service because: unable to locate the paper capture recognition service."

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

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

1. • Go to the location:

     C:\Program Files (x86)\Adobe\<Acrobat Version>\Acrobat\plug_ins\PaperCapture\iDRS15

     For example, for Acrobat DC, go to:

     C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\plug_ins\PaperCapture\iDRS15

   • Copy all the files in the folder.

   • Go to the following location and paste the copied files:

     C:\Program Files (x86)\Adobe\<Acrobat Version>\Acrobat\plug_ins\PaperCapture

   • Go to the location mentioned in Step 1, and copy all the files again.

   • Go to the following location and paste the copied files:

     C:\Program Files (x86)\Adobe\<Acrobat Version>\Acrobat\plug_ins

Try running OCR using the Enhanced Scans tool and then from the Edit PDF tool. (You can select the tools from the right panel in Acrobat.)
