Thank you for posting the solution. I have reported this internally to the developers!

Sorry, further to this it didn't quite work but showed me a work around.

It seemed that the reason the DLL could be found when I reinstalled and launched is because I used the desktop shortcut to nRF Connect to launch the app and then selected Power Profiler. This works every time. However if I use the pull down arrow to create shortcut, and launch from the shortcut, then the DLL cannot be found.

Working Shortcut

Target "C:\Users\awright\AppData\Local\Programs\nrfconnect\nRF Connect.exe"

Start In "C:\Users\awright\AppData\Local\Programs\nrfconnect"

Failing Shortcut

Target "C:\Users\awright\AppData\Local\Programs\nrfconnect\nRF Connect.exe" --args --open-official-app pc-nrfconnect-ppk --source official

Start In ""

SOLUTION

Copy the start in folder location from the nRF Connect shortcut and paste it in the Power Profiler Shortcut.

Now things are behaving as they should from both shortcuts.

That's brilliant, thank-you all is now working as it should.

Just for the record I had not got the folder %LOCALAPPDATA%\Program\nrfconnect, though I did find a couple of others with names that MIGHT have been relevant but probably weren't. I figured it was worth deleting these anyway as part of the clean install.

After uninstalling I deleted the 3 folders below, then reinstalled nRF Connect 2.7.0 and Power Profiler is now working perfectly. Thank you so much for your speedy solution.

%LOCALAPPDATA%\Temp\nrfconnect-driver-install
%APPDATA%\nRF Connect
%APPDATA%\nrfconnect

Hi,

I got this exact error on my system today. I solved it by Uninstalling nRF Connect, deleting the directories %LOCALAPPDATA%\Program\nrfconnect and %APPDATA%\nrfconnect, and then reinstalling nRF Connect. Could you try this?

Best regards,
Jørgen
