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.

Subject: Opening Acrobat 7.0 files in earlier versions

Hi all,

I saved a PDF using Acrobat 7.0 and a colleague tried opening it in Acrobat 6.0 
and got this message:

"This file appears to use a new format that this version of Acrobat does not 
support. 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";

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?
