Trust webcam and NOD

Hi
when tried to install Trust webcam driver(file in the pic below). I got NOD setup window (seems like NOD is trying to reinstall itself again). Why is that. Thanks

Usually and this is the 4th time on wilders forums that I do advice for NO to registry cleaners. I am sure this is a problem caused by a trusted "Regsupreme" which I use on this installation. It showed just now (actually after almost 6 months of last Trust driver installed). What makes me sure one might say. Well, I have an exact Identicall parallel installation (that is 100% identical) apart from Regsupreme the registry cleaner is used on this installation and Not used on its parallel brother. of course NO such problem on the 2nd installation. Just want to let you know. thanks
