This is a ridiculous problem. This never occurred with the previous Acrobat version. This seems to be a huge problem and should be fixed right away. I don't appreciate Adobe staff suggesting a work-around because their pdf creator cannot create a pdf. This isn't a free software. The issue has been reported for quite a while.
Must be very confident to mess around with the registry. I saw a Microsoft Forum in which a user place a minus sign in front of the arcotray registry key code.
