It looks this issue typically happens when you uninstalled a higher version of jlink and then installed a lower version. the registry seems to pointing to the higher version (which does not exist) so a manual edit of the registry seems to be needed. This could be complicated by the fact that the version of jlink being bundled by different nordic tools are often not clear so this can easily happen without the user's knowldege, esp. when downgrading tool versions.

I've the same problem. Looking in the windows register I found a wrong path to J-Link (maybe due to different try of JLink installation).

Verify that in this key [HKEY_CURRENT_USER\Software\SEGGER\J-Link] the string 'InstallPath' has the right path to the Jlink installation folder.

BR.

For those who are facing the JLinkARM.dll ERRORs in nrfjprog, I faced the same problem when I tried to downgrade to previous version of nRF Tools.

I struggled for a few days, and found that it is because there are some residues in the installation folder as well as the windows registry, even I have uninstalled the tools.

To systematically clean up the installation, you need to:

Uninstall all Nordic-related tools and SEGGER-related tools through windows "Programs and Features".
Completely remove the folder "C:\Program Files\Nordic Semiconductor".
Search for keywords "nrf51", "SEGGER" and "JLink" in windows registry, and delete related keys.

Thereafter, you can install Nordic-related tools again.

This is not an answer. Please ask it as a new question, and link to this one if it's relevant.

I have the same problem right now

ERROR: JLinkARM.dll could not be located after the installation info in the registry or in the current folder. Please reinstall JLinkARM software package.

I uninstall all and tried installing fisrt the SDK but it did not work

Is there something else I can do?

Thanks

I faced this problem once when I downgraded from a newer jlink to an older version. The windows registry still pointed to the newer version. I replaced the path with the path of my older version and then it worked.

The main issue here seems to be that you need to install the J-Link drivers before installing the SDK, which adds the nrfjprog.exe utility. Installing things in this order I no longer have issues with nrfjprog complaining about JLinkARM.dll unless it's in the same folder as the Makefile.

I have just found that by editing the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\SEGGER\J-Link and udating the Path to the installed version, nrfjprog was able to find the correct installation. This solved it for me without having to reinstall everything.
