Acrobat X Protected Mode - FSA Access Denied Error

Hi,

We know that Acrobat X Protected Mode causes FSA Access Denied Error. However Customer is not willing to Disable protected mode for security reasons.

One alternative way to Protected Mode is to Whitelist ....but these are the properties that can be enabled in the custom whitelist. Anyone knows which property is causing the FSA PDF error?

Also do you know if the problem exists with Acrobat XI or not? 

Many Thanks
