This issue occurs either if the application is not compatible with your system or if it is not correctly installed. In order to fix it, uninstall the program using its uninstaller or Add or Remove Programs feature (Control Panel > Uninstall a program) and run CCleaner to make sure that there are no leftover registry keys in your system. After that, navigate to the official web page, identify your webcam model, press the Downloads tab and download and install the available files. If it still doesn't work, you can use another webcam capture utility from Software Informer database.
