Adobe acrobat 7.0.5 sdk User Manual

Working with PDF Documents

To open documents using automated processes, it may sometimes be necessary to 
suppress the warning indicating that the version number of the document is greater than 
the version of Acrobat or Reader being used.

To address this issue in the Windows registry for Acrobat, set 
HKEY_CURRENT_USER\Software\Adobe\Adobe 
Acrobat\7.0\AVAlert\cCheckbox\idocNewerVersionWarning to 1. For Reader, the 
registry entry is HKEY_CURRENT_USER\Software\Adobe\Acrobat 
Reader\7.0\AVAlert\cCheckbox\idocNewerVersionWarning. 

This procedure involves editing the registry. Adobe Systems Incorporated does not 
provide support for editing the registry, which contains critical system and 
application information. It is recommended that you back up the registry before 
modifying it. 

To modify the property list entry for Acrobat on a Macintosh, use the property list file 
<user>:library:preferences:com.adobe.acrobat.pro7.0.plist and assign the value 1 to 
<AVAlert><Checkbox><docNewerVersionWarning>. For Reader, the property list file is 
<user>:library:preferences:com.adobe.acrobat.reader7.0.plist.

This warning can also be suppressed interactively by checking Do not show this message 
again in the warning dialog box that appears.

In both cases, bear in mind that PDF files from future versions of Acrobat or other 
sources could conflict with the current version of Acrobat or Reader without 
displaying this warning, although Adobe Systems, Inc. makes every effort to avoid 
such backward compatibility issues.
