I have just installed Adobe Professional version 8 and found that even though Acrobat reader (the pro version) is loading fine with documents either locally or through a browser, LiveCycle 8 will not allow the use of the Preview PDF in the view settings. It is greyed out.
I have checked and the "file system browser" is checked in the tools, option, document handling, file management section of LiveCycle.
I also checked on the edit preferences section of adobe acrobat profession 8 (reader) to see if the browser option was selected there as well. It was.
I am at a loss to identify why I cannot use the Preview PDF in LiveCycle.
I have removed all free reader versions of adobe and have uninstalled and reinstalled as well as repaired the adobe pro installation with no positive results.
opening Adobe Acrobat Professional, go into Edit menu, Preferences, Internet and the box that has Display PDF in browser may/may not be ticked.
If it isn't, tick it and save then go back into Adobe LiveCycle and should be ok. if it already is ticked, un-tick it and save, then go back in and tick again and save - don't know why this works, but it did for me.
Interesting... Adobe recommend disabling the browser PDF display for users with accessibility issues (screen readers and the like). This could be where I came unstuck... I'll try your workaround Jodie, thanks.
