JavaScript console not allowing app.openDoc

I'm using Adobe Acrobat X Version 10.1.16.

Acrobat JavaScript Debugger Functions Version 10.0
Acrobat EScript Built-in Functions Version 10.0
Acrobat SOAP 10.0

I paste and run the following code in my JavaScript console. API.pdf is a JavaScript Acrobat API file, and TestFldr is an empty folder with just that file.

app.openDoc("C:\TestFldr\API.pdf");

I receive the following output in the console.

NotAllowedError: Security settings prevent access to this property or method.
App.openDoc:1:Console undefined:Exec

Furthermore, this code doesn't work in my privileged user folder when saved as a JavaScript file, Config.js. My privileged user folder is as follows.

C:\Users\Trey\AppData\Roaming\Adobe\Acrobat\Privileged\10.0\JavaScripts\Config.js

How can I get around this?
