If you don't have the support CD for your laptop, then you will need to download the package manually. You can do this by first identifying the laptop you're using. Turn the laptop upside down and identify its model number. Paste that number in Google and attach +drivers string. If it's a known laptop, the first like will take you to the official drivers downloading page. From that location, choose Windows Vista as your operating system and download the camera support applications. Install it using the on-screen instructions and the functionality will be restored among the support software.
