Rollback Software renders device not found in master control

[KS Neptune]

Does anyone know how to remove all Nordic software and clean out all registry keys?

Installed mastercontrolpanel.3.9.0.6.x64.msi and all is working great with the RF Dongle. I upgraded the software, found it was working, but kept asking to update the firmware, which I always said no. Didn't like that it kept asking, so I uninstalled it. Rebooted. Installed the original software. Now the dongle no longer works. I also tried another dongle from another system and that one also doesn't work. How can I get the original version of the software to function properly?

Øyvind,

I can not update the dongle on this system, it doesn't show up as a device in the Master Control Software. The JLINK does show up as a device though. I looked at the log, found a problem.

2;07:04:17.3637 [MainThread] Master Control Panel 3.9.0.6 3;07:04:17.3807 [MainThread] Log verbosity level: High 4;07:04:17.5598 [MainThread] nrfjprog.dll 5.2.0.45231 5;07:04:17.5598 [MainThread] Error in PopulateDeviceList: JlinkArmDllCouldNotBeOpened

so.. then I found a link to fix this. Update the following registry entry for each user that uses nRFgo Studio, and it should work:

HKEY_CURRENT_USER\Software\SEGGER\J-Link\InstallPath

Hi,

You can also try updating the JLINK software and documentation pack, which you can find here.

Best regards,
