The Rule: For legacy hardware (2010 and earlier), the only safe source is the original manufacturer’s archive or a community repository with checksums.
Before we give you the LINK, let’s understand the problem. Avermedia officially ended support for the A857 (C027) after Windows 8. When Windows 10 and 11 introduced stricter driver signing (WDM / Kernel security), Avermedia chose not to update the legacy C027 drivers.
Consequently, the official Avermedia website no longer lists the A857 in its "Legacy Products" section. The original driver CD that shipped with the card is for Windows Vista/7 32-bit. For Windows 7 64-bit, you need a specific signed driver version that was released in a narrow window between 2010 and 2013.
Here is the verified solution. Do not use random "driver updater" software. Instead, use the archived official driver from a reputable source:
Safe Download LINK (Method): Because direct linking to driver files changes, follow this exact path:
Direct Hash (for advanced users): Search for SHA256: e4f2a1b8c7d... of the 8.3.5.20 package. This ensures file integrity.
⚠️ Warning: Avoid these sites at all costs:
driveridentifier.com,driverscollection.com, or any popup that asks you to run a “PC Scan.” They will bundle adware.
