Regardless of the Acrobat version compatibility level you use when you generate a PDF, when you do a subsequent save from Acrobat, the header information in the file is updated to reflect the version you saved from even though the contents of the file are still compatible with an older version. In order to retain backwards compatibility when saving a PDF from a new version of Acrobat, you must initiate the final save from the Advanced>Optimize PDF dialog where you have set the desired compatibility.
My opinions only; I don't speak for Intel.

It may not open or display correctly. Adobe recommends that you upgrade to the latest version of Acrobat products. Please visit our products site at http://www.adobe.com/acrobat." I referred back to the document and noticed that I did in fact save it so that it would open in Acrobat 5.0 or later. I don't like our users seeing that message (and many of them use Acrobat, not Reader, to read our docs). Anything we can do about it? Jon Harvey Manager, Desktop Documentation ?
