  • Antivirus Interference: Antivirus software (like Windows Defender) often flags loaders as "HackTool" or "Trojan" because they modify the software's memory. You may need to disable your antivirus temporarily during installation or add an exception for the VCDS folder.

  • Firmware Updates: Be very careful with the "Firmware Update" button inside VCDS. If you are using an older interface, updating the firmware via a loader environment can sometimes "brick" the cable or put it into a state where it requires an official license to recover.
