- If you see "License Revoked" or the software fails to start, you may have run the original VCDS executable previously or your antivirus may have interfered. In such cases, completely uninstall VCDS, delete the C:\Ross-Tech folder, restart your computer, and repeat the installation from the beginning.

- Once the loader is running and the software launches, go to Options → Test. The system should automatically detect your interface. Click Save to store the configuration.

Install the software to the default directory (usually C:\Ross-Tech\VCDS ).
