Hi Edward, The ask is basically that after your testing is complete you will have to replace the PPKLite file shared by Vinod with the original one @ location C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\plug_ins . This is a necessary step if not done any future Acrobat updates might fail. In case you have not taken a backup of the original PPKLite.api. Simply delete the file from location C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\plug_ins and repair Acrobat. For repair perform the following steps: Open control Panel-> add or remove programs Right click Acrobat and select change-> next Select Repair and perform the repair This would place back the original file Thanks, Rupa Jannela Acrobat Team ...
