The cmd window flashes by for me too.
You can try this:
Remove the USB Wireless adapter from the laptop.
Uninstall the Belkin drivers
Restart the laptop
to remove each entry that shows Belkin
(There might only be one or maybe none.)
Restart the laptop if you removed anything
Reinstall the Belkin drivers.
Attach the USB Wireless adapter only after the install program asks for it.
