I have a pdf form that uses Acrobat 8 features. The form contains Javascript that interacts with the hosting web page.
Some of my Windows users have both Adobe Acrobat and Acrobat Reader installed, and need Adobe Acrobat to be the default handler for pdf files. The users with Adobe Acrobat 7 are unable to use the form, even though they might have Acrobat Reader 8 or 9 installed.
Currently, the PDF is embedded like this:
<object id="host" data="/path/to/document.pdf" type="application/pdf" width="900" height="550" ></object>
