NRF Connect

Jayhumbard

I have installed the NRF Connect app on my Windows 10 PC, using "Run as Administrator" and keep getting the following error message whenever I try to install any of the products using the INSTALL buttons in the NRF Connect app:

The Error says: Unable to install:  Error invoking remote method 'apps:install-downloadable-app': Error: spawn UNKNOWN

Most computer settings are managed by IT for all sorts of corporate security.  I'm sure we are behind firewalls, etc. I was advised to use run as administrator to allow it to install (the command line tools seems to have installed using this method).     I have tried uninstalling and reinstalling, and also tried rebooting several times. 

Any ideas?

    Hi

    Three things you should try in the following priority:

    1. Delete nrfutil.exe from %APPDATA%\nrfconnect\nrfutil.exe, close the nRF Connect for Desktop app and reopen it. This will re-add the file and would fix it in case it's broken.

    2. This error could be caused by antivirus quarantine, and you should check with your IT department. Especially since this is the second time AFAIK your company specifically reports this issue.

    3. execute the command %APPDATA%\nrfconnect\nrfutil search  in your command line and let us know whether does it shows an error or the installable nrfutil commands.

    4. Let me know what apps you want specifically and I will try to provide the specific files for you that you can install manually onto the nRF Connect app with the "Add sources" option in SETTINGS.

    Best regards,

    Simon

    Hi Simonr! 

    i have been having the same issue stated in this post. We are only trying to install the "programmer" utility in the nrfConnect Desktop app. And i have followed the instruction mentioned in this post.

    • for the command %APPDATA%\nrfconnect\nrfutil: C:\Users\XWEI>AppData\Roaming\nrfconnect\nrfutil
      This program is blocked by group policy. For more information, contact your system administrator.
    • So i moved the whole nrfconnect folder to C:\ dir directly and got the message:

    C:\>nrfconnect\nrfutil
    nrfutil

    Usage:
    nrfutil [+MODIFIER] [OPTIONS] [SUBCOMMAND]

    Options:
    --log-level <LOG_LEVEL> Set the maximum log level [env: NRFUTIL_LOG=] [possible values: off, error, warn, info,
    debug, trace]
    --log-output <LOG_OUTPUT> Set log output type: --log-output=stdout --log-output=file ... [possible values: file,
    stdout]
    --json Print output in a JSON Lines format
    --json-pretty Print output as formatted JSON
    --skip-overhead Skip all message overhead when in JSON output mode, outputting only the data part of
    "info" messages and ignoring the rest
    --changelog Print the latest changelog entry
    --changelog-full Print the full changelog
    -V, --version
    --help-extended Show comprehensive documentation
    --license Show license information for in-built dependencies
    --detect-proxy Invoke libproxy's 'proxy' utility program to retrieve proxy server info and use it
    -h, --help Print help (see more with '--help')


    Built-in nrfutil commands (see installed commands with `list`):
    help Show comprehensive documentation
    install Download and install nrfutil commands
    upgrade Upgrade nrfutil commands to the latest version
    uninstall Uninstall nrfutil commands [aliases: remove]
    prepare-offline Prepare local package and resource repositories for offline installs of nrfutil commands
    search Search for installable nrfutil commands in the package index
    list List installed nrfutil commands
    self-upgrade Upgrades the nrfutil core functionality to the latest version

    • i also changed the directory in the property of the "nRF Connect for Desktop"
    • However, i was still having the same problem when installing the "programmer" utility:

    Our IT suggested to check with you to see if you can provide me the specific files for "programmer" utility that we can install manually onto the nRF Connect app with the "Add sources" option in SETTINGS.

    Thank you!!

    Hi I only have the file as a .tgz link here (https://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/pc-nrfconnect-programmer-4.2.0.tgz)

    for you. We don't have each file available manually I'm afraid. Does your group policy also say you can not execute applications from the APPDATA folder?

    Best regards,

    Simon
