| Symptom | Likely Cause | Potential Solutions | | :------------------------------------------ | :------------------------------------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | VCDS does not recognize the interface | Incorrect driver installation, incompatible cable, or loader not running. | Ensure you installed the . Reinstall the drivers via the VCDS installer. Try a different USB port. Confirm your cable has a compatible STM32F405/STM32F429 chip ; if it has an ATMEGA chip, this software will not work. | | The loader is immediately deleted by the PC | Antivirus or Windows Defender is active. | Disable all antivirus software and Windows Defender before extracting and running the loader. Add the entire VCDS installation folder and the loader's folder as an exclusion in your antivirus settings before re-enabling it. | | VCDS launches but Security Access fails | The 64-bit version of VCDS was installed, or the loader is not active. | Uninstall VCDS and reinstall, ensuring you select the 32-bit executable option during setup. Always launch VCDS through the VIIPlusLoader , not directly from the VCDS icon. | | "Illegal Device" or "Revoked License" error | The loader's emulation has been detected by the software. | This is difficult to resolve. Some users suggest completely uninstalling VCDS and the loader, cleaning the registry, and starting the entire installation process from scratch, ensuring you remain offline. There is no guaranteed fix. | | The cable's firmware update fails or bricks | Incompatible loader for the cable type, or the update process was interrupted. | Prevention is critical. If the cable is already bricked, recovery is difficult and often requires specialized hardware knowledge (e.g., using an ST-Link programmer to reflash the chip). This is generally beyond the scope of standard user troubleshooting. The cable is likely damaged. |
