This is what worked for me also (uninstall 64 bits and install 32 bits), so it's not fixed by now

This is so weird I also first installed 64 bit tools , after reading this post I uninstalled 64 and installed 32 bit and it worked, this is ridiculous and frustrating. Thanks for the post though else I would have wasted even more time on this. And why does Nordic Studio itself provided the latest command line tools so that the user doesn't have to figure out all this frustrating stuff.

I have the latest version of nrfjprog with NRF52840 support (9.8.1). But even I click download NRFgo Studio - 64bit 1.2.1 - now reinstalled nrfgostudiowin641212installer.zip. It installs Program Files (x86). NRFTools are in Program Files. So that means that your NRFgo Studio is 32-bit application, which cannot link dynamic library nrfjprog.dll. Is it so hard to make it right? Please fix it and compile NRFgo Studio for 64-bit architecture, then fix your download link. Thank you very much. I wasted hours on this.

To clarify I had the 64 bit version, the 32 bit is what worked for me (that's the suggested link given by tech support)

Hi Rando,

Have you try to uninstall and install the nRFx Command Line Tools again? Try installing the newest version -> https://www.nordicsemi.com/eng/nordic/Products/nRF52840/nRF5x-Command-Line-Tools-Win32/58850

Best Regards,
