    Hello manojroy123 It appears that you are having a lot of difficulty with Circuit Python - it's great that you're asking for help on the element14 Community, and where possible other members will chime…

    As expected as the documentation clearly tells you that the signing certificate has expired:

    Did you try installing the drivers from https://learn.adafruit.com/welcome-to-circuitpython/windows-7-and-8-1-drivers ?

    This Adafruit troubleshoot page for 7 and 8 has a slightly slightly different process: https://learn.adafruit.com/circuit-playground-express-circuitpython-5-minute-guide/connect

    Maybe worth a try, manojroy123 ?

    I believe that was already done back here:

    /technologies/internet-of-things/f/forum/54886/serial-port-is-not-opening-in-mu-editor-for-circuit-python

    "...I am using circuit python and have installed all the adafruit drivers for serial port but still not showing serial terminal..."

    However I suspect that installer may not know about the nRF52840 DK board.

    or any other board after Nov 2020, hence:

    maybe this is  similar to Arduino Uno R4 support under Arduino IDE, that under Win7 had driver problems and needed to be used under Win10...
