AVerMedia’s official support site is the safest place to download drivers. Look for model A857 and select drivers compatible with Windows 7 64-bit. If an official Windows 7 driver is not listed, use the most recent driver AVerMedia provides for similar A8xx models but confirm it lists Windows 7 x64 compatibility before installing.
(If the official AVerMedia page is unavailable or the model is discontinued, reputable driver-archive sites or the manufacturer’s FTP mirror are alternatives — verify file checksums and avoid sites that bundle unwanted software.)
