Issue
Installing Reader 9.1 modifies Registry permissions for key HKEY_CLASSES_ROOT\Interface\{34A715A0-6587-11D0-924A-0020AFC7AC4D} from “Full Control” to “Read“. This modification prevents a successful installation in enterprise environments where customized installer files are used. The mentioned key is a part of the Internet Explorer installation and applications that work with the web browser events use it.
The Access Control List for this key before installation is as follows:
BUILTIN\Users=Read
BUILTIN\Power Users=Special
BUILTIN\Administrators=FullControl
NT AUTHORITY\SYSTEM=FullControl
CREATOR OWNER=FullControl
Following installation it has been changed to:
BUILTIN\Administrators=Read
NT AUTHORITY\SYSTEM=FullControl
Everyone=Read
Solution
Upgrade to Adobe Reader 9.4 or Adobe Reader X. Do a full installation of one of these versions to apply the fix.
As a workaround, you can modify the MST file with Customization Wizard to prevent the permissions on this key being changed.
