Adobe Reader DC – Tool Panel Doesn’t Go Away

Problem:

The tool panel doesn’t go away and it’s annoying.

Solution:

(h/t Mark R)

  1. Go to the install directory, i.e.” C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroApp\ENU”. Create a new subfolder (I used “Disabled”).
  2. Move 3 files from the “ENU” folder into the new “Disabled” folder:
    1. AppCenter_R.aapp
    2. Home.aapp
    3. Viewer.aapp.
  3. Open a PDF and no more Tool Panel !
