Simply download the exe file and run the exe file to use the software.
WebcamViewer is a very simple click-and-run application, where you don’t have to install the application. You can download the software from the link at the bottom of this post. Therefore I decide to develop a very simple webcam software called WebcamViewer that enable you to have a view on your webcam. Unfortunately, under Window Vista and Window 7, this feature has been removed, and if you want to have a view on your webcam, you will need a webcam software.
If you ever use Window XP + Webcam, you probably know that you can view the webcam under My Computer, without any application or webcam software.
