I have updated my Adobe Reader X last week ( April 2012 ) and since then I am having trouble viewing 3D PDF on my web browser, both IE 8 and Firefox. I am using Windows XP.
The warning message I got are shown as follow:
"Some features have been disabled to avoid potential security risks. Only enable these features if you trust this host: (and the hosting website of the 3D PDF goes here)"
Adobe Reader X will allow me to view the 3D model when I select "Trust this host one time only", but it does nothing if I choose to "Trust this host always".
Any help will be greatly appreciated.
Would it be possible for you to share any public URL for such a PDF so that I can check the same at my end.
Also, can you check if there is any entry for any site in the Trust Manager panel (Edit > Preferences > Change Settings)
Just click on the "View 3D Model" button and it will bring up another window/tab with a 3D PDF.
I will try changing the setting in the Trust Manager panel when my Windows XP computer is available later today.
The real problem is not Adobe Reader X, but rather Adobe Acrobat 9. I have both Adobe Reader X and Adobe Acrobat 9 installed on my Windows XP machine; and all PDF files are associated with Adobe Acrobat 9.
I will update this discussion when I get more information.
