In order to fix the problem, I recommend you download the latest webcam files from the official web page. Select your operating system and download the files. After that, press Windows + R key combination, type devmgmt.msc and click OK. Expand the Imaging devices list, right-click on the webcam driver and select Update Driver Software. Use the Browse option to navigate to the downloaded package, select the driver and install it following the on-screen instructions. After that, update ArcSoft WebCam Companion to the latest version.
