Problem:
The tool panel doesn’t go away and it’s annoying.
Solution:
(h/t Mark R)
- 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”).
- Move 3 files from the “ENU” folder into the new “Disabled” folder:
- AppCenter_R.aapp
- Home.aapp
- Viewer.aapp.
- Open a PDF and no more Tool Panel !
