32bit graphics mode for Guest virtual machine

Hi,

Working in a project I got a question that I was unable to answer myself, so I turn to the experts :)

We have an environment running with Hyper-V 2012R2 and guest that run Windows 2008R2. 

Google earth has to run inside the Guest vm to be accessed via Citrix XenApp.

Google Earth requests a 32bit graphics mode to be installed.

So far no harm done.

What we noted was that we only could select 16bits graphic modes in the guest vm, running Windows 2008 R2.

The question is simple yet I can't find the answer, is it possible to have 32bit graphic mode options in a guest vm running 2008R2 with Hyper-V 2012R2?

hope you can shed a light on this

I've included the screenhot so you see it only shows 16bit modes.

Thanks for the help

Greetings

Rob
