While installing MessageStats via Remote Desktop Session on a virtual machine placed on a physical host the following message is displayed:
'Quest MessageStats requires a resolution of at least 800 by 600 pixels'
Ensure that both the settings of the host and of the Remote Desktop session are at least 800x600.
Alternatively run Remote Desktop client using /Admin switch - Start - Run - mstsc /Admin /f (/f Starts console in Full Screen Mode)
