nRF Connect unable to complete installation of SDKs

I'm stuck trying to set my nRF Connect extension on VSC. I've followed the guide for the installation but I'm reaching a wall. Every time I try to install a given SDK I have the same result (see pictures) I end up having an error.

It seems a common thing because I've searched for it for some time finding several posts of similar errors as mine I've tried the different pipelines in the blogs but I none work for me.

I've tried to use a previous version of nRF Connect, installing from GitHub repository, unstalling and installing the nRF extension in vsc, tried to extract manually the sdk files, even to rename the python.ext in appdata.
The one thing I haven't tried yet is to deactivate the firewall because I'm not able to do so as the computer is from my enterprise and I don't have permissions to do so.

Images of the last try:

  • Hello,

    I don't see the actual error message from your screenshot of the output window. Could you please try installing the SDK from the command line using the command below and post the output here it reports any errors?

    nrfutil sdk-manager install v3.3.0

    nRF Util documentation: https://docs.nordicsemi.com/r/bundle/nrfutil/page/sdk-manager-command 

    Best regards,

    Vidar

  • Hello Vidar

    Thank you for your awnser, but there's no error message on the output window. The last line on the oputput is the one on the photo, then the message pop-up on the second photo appears on vsc.

    Here's the output: 
    Using the global server for downloads. Use '--region cn' for the server in Mainland China.
    [00:00:00] ###### 100% [Install toolchain v3.3.0] Toolchain with version v3.3.0 already installed [00:00:00] ###### 100% [Install SDK v3.3.0] SDK with version v3.3.0 already installed

    Now I'll try to unistall another sdk just to try.

    Regards,
    Oriol.

  • Hello Oriol,

    So the output indicates that this SDK version and toolchain is correctly installed already. Have you checked if the SDK folder (default: c:/ncs/v3.3.0) folder exists or not (you can run "nrfutil sdk-manager list --all-fields" to verify which path it is installed under)? Also, what is indication is not installed?

    Regards,

    Vidar

  • Here's the output after trying to install the v3.3.1:

    nrfutil sdk-manager install v3.3.1
    Using the global server for downloads. Use '--region cn' for the server in Mainland China.

    A list of the affected paths has been written to: C:\Users\ORIOLT~1\AppData\Local\Temp\nrfutil-sdk-manager-symlinks-q83zVe.txt

  • This also looks to have been installed correctly. What are the indications that it is not? Are you not able to select the SDK in the VS code extension?
