I am sending identical FDF forms to two client PCs - one with Windows XP and the other with Vista. Both PCs have Acrobat Reader X and Internet Explorer 8. The FDF file references a PDF form up on a website.
The FDF form opens okay on the XP machine, but on the Vista machine, the PDF opens without any data.
Can you think of any reason why this could happen?
I think I found my problem. There was a difference in the way Adobe Reader was set up in the two computers. Once I went into Edit - Preferences - Security (Enhanced) and put my website in the "Privileged Locations" box, it started working on my Vista machine.
