Deploy Flash 10.1 silently via GPO

[TheReasonIFail]

So I applied to be able to redistribute the player, got approved and downloaded the MSI.

Setup a GPO to deploy it.

When the PC reboots it's shows me it's installing the MSI but when I login I get the screen to approve the eula and to click "next" to install.

Is there anyway to make this happen silently?

I can't seem to find anywhere in the "Software Package" listed in the GPO to add switches.
