Plug in the MVCI device via USB.
Open Device Manager → find “Unknown device” or “MVCI” with yellow mark.
Right-click → Update driver → Browse my computer → point to the extracted folder.
Select Include subfolders → Next.
- Confirm installation of “J2534 Pass-Thru” driver.

🔐 Security & Legal Note

These drivers are often unsigned and may contain code from third-party developers. Use only in an isolated diagnostic environment (not on a daily-use PC).
Ensure you have the legal right to use the MVCI hardware and associated OEM software.

Final check: After install, restart your PC once more before launching any diagnostic application. If the device still fails, test on a clean Windows 10 LTSC or Windows 7 x64 (most compatible).
