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 (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

  2. Copy all the files in the folder.

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

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

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

  5. Go to the following location and paste the copied files:

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