I just ran into this same problem. I installed Win7 Home Premium x86 and after all the Windows Updates, the only device missing - and one yellow bang in Device Manager - is the webcam.
I tried the site listed above, but it never finishes scanning my system. The driver and/or application for the webcam isn't listed under the normal support.dell.com downloads nor is it on the Driver CD.
So, I'm stuck with no way to configure the webcam. Any other suggestions from those that have reinstalled their 1012?
