Mac Logitech Dinovo keyboard's fn keys do not adjust volume, brightness, etc

[The7Fallen]

Hi,
I have recently put windows 7 professional on my aluminum macbook, installed all the drivers, and so forth. I hook up my macbook up to an external monitor, and use a logitech dinovo keyboard for a mac. However, when I am in windows 7, the function keys do not adjust volume, brightness, and any other of the functions. Is there a solution?

Thanks,

try pressing the fn key as well as any one of the function keys (F1, F2 etc)

I have tried this already, with no results. if i open my laptop and use those function keys, they adjust volume and brightness, but i have the problem of needing to open or leave it open every time i want to adjust it.
