"Ports (COM and LPT)" and using the right mouse button select the not correctly installed COM port ("UA 400
COM Port" or "WR 300 COM Port"). Then click on "Update Driver" and follow the instructions in the dialogue
that opens; then the driver should be correctly installed.
Windows 7 / Windows 8 / Windows 10: Open "Control Panel", under "Device Manager" there, select "Ports
(COM & LPT)". Then proceed as described above.
