What is the price for ArcSoft WebCam Companion 3?
You can download the application through the download page at Software Informer, but the problem is related to purchasing. There is no way to buy the software anymore. For some products, the software arrived with your Sony laptop, and ArcSoft sold it separately for a limited time.
You can use the following link to download it, but that's it. No purchasing or support is possible anymore: http://arcsoft-webcam-companion.software.informer.com/download/
