2. Search for "A857" or "DVD EZMaker 7".
3. If you see a list of operating systems, select Windows 7.
4. Important: If you do not see a specific "Driver" link, look for a link labeled "SDK" or "BDA Driver". For the A857 model, the driver is often packaged inside the SDK (Software Development Kit) zip file.

Safety and best practices

• Always download drivers from trusted sources.
• Create a System Restore point before installing drivers so you can roll back if something goes wrong.
• Keep a backup copy of the driver installer on an external drive.

Why Is It So Hard to Find the Avermedia A857 Driver for Windows 7 64-bit?

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.

Troubleshooting: Why isn’t my Avermedia A857 working on Windows 7 64-bit?

Even with the right LINK, you might encounter these issues:

| Problem | Solution | | :--- | :--- | | Code 52 (Driver not signed) | You forgot Step 2. Reboot into F8 > Disable Driver Signature Enforcement. Make this permanent via bcdedit /set testsigning on in CMD (Admin). | | Device shows but No Video | The A857 does not support HDCP. Disable HDCP on your source (e.g., game console or set-top box). | | Audio is missing | Go to Sound Settings > Recording Tab. Set “AVerMedia HD Capture Audio” as the Default Device. | | Blue screen (BSOD) on Windows 7 | You installed the 32-bit driver. Ensure you downloaded the 64-bit version. |

Introduction: A Legacy of Quality Capture

In the golden age of analog video capture, Avermedia was a titan. The Avermedia A857 (often referred to as the "EZMaker" series or similar PCI/PCIe hybrid cards) was a workhorse for video enthusiasts, security professionals, and educators who needed to digitize VHS tapes, camcorder feeds, or composite video sources.

However, technology moves fast. With the advent of Windows 10 and 11, many users have been forced to leave behind perfectly functional hardware. But what if you are still running Windows 7 64-Bits? Whether for legacy software compatibility, industrial machinery, or a dedicated retro-PC build, getting the correct driver for the A857 is a nightmare of broken links and shady driver download sites.

2. Look for "Unknown device" or "Multimedia Controller" with a yellow exclamation mark.
3. Right-click it > Update Driver Software.

5. Click "Let me pick from a list of device drivers on my computer".
6. Click "Have Disk".
7. Browse to the folder you extracted and select AVer850_x64.INF.
