GoZ 4 installation fails on Mac with Maya 2011

When trying to install GoZ I am getting an error that states:
An error occured during installation of GoZ for Maya
(/Applications/Autodesk/maya2011/Maya.app) :
An error occurred during installation.
One possible cause could be unsufficient permissions in target application installation folder.
Please run ZBrush as an administrator and try again to install the GoZ application!

The problem is that I am running as an administrator and as root and am not prompted for a password at any time. I’ve read through the thread about GoZ install issues and have not found a clear solution.
I’m running this in a student lab environment and can’t set the systems up for everyone to have full access to the Maya, ZBrush, or any other application in the Applications folder.
How do I resolve this to get GoZ working? Thank you.

Anyone have any tips? Thanks.
