If your card has dual outputs, the driver software should come from card manufacturer or nVidia. It is included with drivers to support dual displays, you just have to configure drivers in the display options, and you got it.
You don't need to use ATI's application for dual monitors unless you're mirroring them. ATI sets their cards up as primary and secondary displays so anyone can easily use windows Display Manager, clicking on the disabled monitor, then checking the box "Extend my desktop to this device", clicking apply, and dragging the monitor to the position you want it in relation to the original display.
For nVidia dual displays you have to use nVidia's application, which can be found by bringing up nVidia's custom configuration window. Right click on the screen, choose the nVidia display manager tab, and it brings up a custom box with all the options required to figure it out.
That's not the proceedure nVidia uses. He has an nVidia card, for which modern nVidia drivers will configure as a single display in Windows. He needs to use the nVidia application, named nView, as seen HERE
Notice this is a separate menu, not the normal windows display manager setting you'd use with dual cards or an ATI dual output card.
