Dell Smart Card Keyboard (model RT7D60) driver installation

Hi,

I am trying to automate the installation of the Smart Card reader driver for the RT7D60 keyboard. I have the resource CD which has the follwing installation files:
                    GKUPRO2D.cat
                    GKUPRO2D.INF
                    GKUPRO2D.sys
                    ReadMe.txt
I have read the readme file which only gives instructions on how to install the driver through 'Add/Remove Hardware' wizard or via Device Manager.
I have also tried to install the driver by right-clicking on the INF file listed above then choosing install, but nothing happens.

This occurs on both Windows XP SP3 & Windows 2000 SP4, and on all the models of dell computers that we have. I have also downloaded a copy of the driver from the Dell website but this makes no difference.

I have to install around 5,000 of these keyboards to install and it would make much more sense to automate the driver installation. Can anyone please help?

Thanks,

Steve
