[mat-dev] error: mat: Permission denied

Hi,

I have tried installing MAT on my computer (Windows 8) but have encountered "error: mat: Permission denied" when running "setup.py install" on the command line as an Administrator.

May I know what can be the reason and if there's a solution? 

Below is a link to the error.
