I had the same issue and solved it by turning of Acrobat readers "Protection mode".
This is found in the general section in the preferences.
You can google this but as I understand it is a "Sandboxing technology to isolate the application and tightly controlling its resources."
Thank you! This works just fine.
Nice of them to tell us. Programmers trying to be clever, I suppose... But a damned nuisance to every user who wants to open multiple PDF documents from Windows Explorer; i.e. most of us.
In my case: v10.1.1 would not open more than one pdf at a time on a user workstation (although mine did) so I tried disabling protected mode and made sure the large image display setting was correct.
To no avail. Reinstalled version base version 10, checked the same settings...no joy
Also tried repairing the install and re-updated from the base v10...still no love
Solution for me: Opened reader X, under Help-->Online Support, there is an option to generate a system report which availed the following:
Graphics Card: NVIDIA GeForce FX 5200
Check: Not Supported
And of coarse the most recent driver was already present. Had to go back to v9.4
All good now. Hope this saves someone a few hours!
In Adobe Reader Settings
Go to "Window" -> "New Window"
Does that work ?
I am a very unhappy Adobe customer at this moment!
These little "security enhancements" have broken a critical production app that runs here daily causing us to have to manually print the documents when we come in in the morning. As a result the documents are late going out and many, many people people are sitting around twiddling their thumbs. Can anyone say "lost productivity"!!!!
We are STILL after a week of effort, looking for a fix or work around!
