Install application with unsigned drivers

[mrloopy]

Hi all,

I' trying to install Intel's Desktop Utilities (IDU). I have a batach script that's called suring specialize phase that runs the setup.exe -s. However, when the unattend install gets to installing IDU, it pops up a security alert with Windows can't verify the publisher of this driver software and I have to accept it (twice!) to continue.

Does anyone know how I can get unattend install to ignore unsigned drivers?

Thanks!
