Windows Server 2008R2 Aero

I am virtualizing a Windows Server 2008 R2 Enterprise on parallels 7. I have a Retina MBP i7 8GB memory. Is there any way to enable Aero on this virtual machine? I have already added desktop experience, but the Aero option is greyed out. Is there any way to enable this option, and if so how?

 

Install Parallels Tools.

 

Parallels Tools is Installed

I have installed parallels tools, desktop experience, and it will not let me select aero.

 

Make sure that the Theme Windows Service is started. By default it is disabled on Windows Server...
