Q: How can I confirm if the driver is successfully installed?: A: If VXDIAG Manager can read the device's serial number, the installation is successful. If not, please contact support for assistance (e.g., via TeamViewer/Todesk).
Q: Does the device support virtualized Windows 7 X64 systems?: A: No, virtual systems are not supported. If you are using a virtual machine and encounter compatibility issues, please switch to a native Windows 7 Professional 64-bit installation.
Q: What are the supported car years for Volvo models?: A: The device supports Volvo vehicles from 2000 to 2014. It does not support vehicles older than 1999 or newer than 2015.
Q: My license shows as "invalid" or "expired". How do I update it?: A: First, ensure your VX Manager client software is up to date. Then, update the device firmware, and finally, update the license through the "Update license" option in VX Manager. Ensure the device is connected to the OBD2 port during this process.
Q: VX Manager shows a "NO Device" error.: A: Click the "Reconnect" button in VX Manager. Check your computer's Device Manager (Right-click Desktop > My Computer > Manage > Device Manager > Network Adapters) to see if "Realtek USB" is listed. If not, ensure the USB cable is securely inserted into both the device and a working USB port on your computer. Try a different USB port. The device should emit a "drip" sound when it starts successfully. If VX Manager then displays the device serial number, the connection is successful.
