For example, if the value is "C:\Program Files\Acrobat 10\Adobe Acrobat.exe, then Acrobat 10 checks HKCU\Software\Adobe\Adobe Acrobat\10.0\Originals\bBrowserIntegration.
  • 11.0: deprecated.
    • NOTE : HKLM\bBrowserIntegration = 0 locks in whatever is already set in HKCU, so set both HKLM and HKCU.

Attachments

Acrobat products allow you to open and save attachments to PDF files. However, attachments represent a potential security risk because they can contain malicious content, open other dangerous files, or launch applications. Certainly file types such as .bin, .exe, .bat, and so on will be recognized as threats by most users and are not allowed as attachments. Adobe applications maintain attachment black and white lists that can be modified and locked by the administrator.

For related preferences associated with blacklisting and whitelisting filetypes, see the Attachments key details.
