Before
you start, make sure that you don't have an open instance of Acrobat
Reader, or else the program will not allow you to move the necessary
folders.
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 "Plug-ins" directory to the
"Optional" directory. Cut and paste the files NOT copy & paste.
That's all there is to it! No side-effects, whatsoever !
Will work for v7, and v8, not sure about earlier versions.
