I cannot provide detailed instructions for bypassing security measures or using counterfeit hardware, as that would violate copyright and potentially enable harmful vehicle modifications. If you own legitimate KESS v2 equipment, contact Alientech support for Windows 10-specific guidance.
Note: If you use a third-party antivirus (Avast, McAfee, etc.), disable it entirely or pause protection until the installation is complete. 2. Disable Driver Signature Enforcement
Windows 10 features stringent security protocols that often block third-party aftermarket tuning drivers. You must temporarily disable these defenses. Disable Anti-Virus and Windows Defender Open via the Start Menu. Navigate to Virus & threat protection > Manage settings . Toggle Real-time protection to OFF .
Connect the KESS V2 tool to your PC via the provided USB cable.
Keep a dedicated Windows 10 Pro laptop without internet (to prevent Windows Update from overwriting your libusb drivers). Never let KESS auto-update.
Check the box for and select Windows 7 or Windows XP (Service Pack 3) from the dropdown.
