: If the device still isn't recognized, try a different USB port (preferably a USB 2.0 port, as 3.0/3.1 ports sometimes cause timing issues with MTK VCOM drivers).

: If you see this in Device Manager, right-click the entry, select "Update Driver," and manually point the wizard to the folder where you extracted the AIO pack.

: Many older drivers in the 2019 pack are not digitally signed by Microsoft. You must temporarily disable signature enforcement via the "Advanced Startup" settings to allow Windows to accept them.
