Since installing Adobe Reader X, I am unable to open pdf's attached to emails (in Outlook 2010). On double clicking the attachment, Adobe Reader opens and I get the following message "There was an error opening this document. Access denied."
If Adobe Reader is already running when I double click the attachment, it opens OK. If I save the attachment to my HDD, it also opens OK, when I double click it (whether or not Reader is running or not).
I would very much appreciate help with this problem.
My desktop is running Windows XP 32 bit with Outlook 2010 32bit. I'm a local admin on this pc.
