1. Go to the installation folder of acrobat reader
(C:\program files\adobe\acrobat\reader\.. whatever)

2. Move all the files and folders from the “plugins” directory to the “Optional” directory. (I repeat.. cut and paste the files NOT copy & paste).

Note: Make sure that acrobat reader is not open else it will lock the files and not allow you to move the files).

Editor comment : Works like charm!
