Sphere Af Und I-catcher I Have A Logitech QuickCam Sphere AF, And I Have Trouble Installing?

I have a Logitech QuickCam Sphere AF, and I have trouble installing? - sphere af und i-catcher

I installed before perfection, but has not been working lately, so I installed. I have installed, as I always do, but does not work? Halfway through the installation, I always restart my computer, and when he returned to the webcam I told him that followed is what I do. (I have a few windows, get new materials) all at once, but the installer can not find the webcam. (I have tried to attach the webcam on Windows new hardware, but no luck.) Any suggestions?
