I'm having the same problem. I cannot open any PDF files on my mapped network drive, but I can open them if they are on my harddrive. Same error message "There was an error opening this document. Access denied."
I'm running W7 Enterprise
Same here. I was able to fix this problem as follows:
Edit - Preferences
Then under the Categories list on the left, select "General"
Uncheck the last box titled "Enable Protected Mode at Startup"
I did this and I can open any file, locally or on LAN...
Hope this helps!
I sure wish Adobe would fix all the other bugs!!!
