Step 3: Bypass Driver Signature Enforcement (Windows 10/11)

Windows often blocks unsigned or legacy industrial drivers by default. If the installer fails or the device doesn't work after plugging it in, you may need to disable driver signature enforcement temporarily:

1. Press Windows Key + X and hold Shift while clicking Restart.
2. The PC will reboot into a blue menu. Select Troubleshoot.
3. Select Advanced options > Startup Settings.
4. Click Restart.
5. When the PC reboots, press F7 (or number 7) to select Disable driver signature enforcement.
6. Once Windows loads, install the driver as described in Step 2.

, as this is often required for secondary software compatibility. Disable Fast Startup

Step 3: Verify Before Running

• File size: Should be between 5MB and 30MB. Anything smaller than 1MB is likely a stub installer.
• Antivirus scan: Upload the file to VirusTotal (virustotal.com). A verified driver should have 0 detections from all 60+ engines.

: If you are developing custom software, ensure you use the official ControlCAN.dll found in the ZLG secondary development library Third-Party Tools

7. Red Flags – When to Reject a Driver

• No WHQL / EV signature – high risk.
• Driver file > 2 MB – suspicious (original < 1 MB).
• Install requires disabling Defender or UAC – immediate abort.
• Installer bundled with “Baidu Browser” or “360 Safe Guard” – definitely tampered.
• ControlCAN.dll has exports but no VCI_InitCAN – fake stub.
