Thank you rjjoshi, I got it. Adobe Reader was disabled in CHROME. So I
Enabled it. Now it's working for both local and remote Livecycle PDF
forms.And I did the similar thing for Firefox as attached. The Livecycle
form will be downloaded from Firefox then opend by Adobe Reader instead
of being opened in Firefox, which works fine. However when I change the
Action to Preview in Firefox. The problem will be like the 2nd attached
screen shot.
