Problem with fingerprint reader

I am using Dell Studio 1535 with Windows Vista Home Premium 32-bit on it. Recently, my fingerprint reader stopped working. From other forums, I found HP fingerprint software, and it worked well for the time being. But I want software from Dell itself. I uninstalled Authentec Fingerprint driver and restarted the laptop. Windows automatically found new hardware, but it failed to install properly. I downloaded Authentec Fingerprint Driver from Dell's support website, but it said "This is is multi-disk installation file. Please insert the last disc."

How can I get my fingerprint device to work again with Dell's own software/drivers?
