Thank you for the reply. I understand that the 2nd user can change their default PDF app to match whatever the 1st user has. Is there any way around this? When you have a regular PDF in windows explorer, you can just use any PDF reader to open it no matter what. Yet, for embedded PDFs in Word, you have to use the same app that the person who embedded it used. I think it may be unsolvable, and we would just have to have everyone on the same PDF reader app.
