I have a computer that is running windows 7 64 bit. They are using adobe acrobat 8 pro to scan documents into pdf's. Up until a couple of days ago they had no issues. Now all of a sudden when they click the scanner from the drop down it locks adobe acrobat up and I have to end the job in task manager. It works fine on the admin side. I have given all the folders pertaining to adobe full rights to everyone and the user. Here is a screen shot.
