Problem installing nRF util

[Yano]

Hi, I'm trying to install nRF util but I'm getting an error.

C:\Develop\Well water\Firmware\PSU rev 3\nRF5SDK1702d674dde\nRF5_SDK_17.0.2_d674dde\external\micro-ecc>nrfutil pkg generate --hw-version 52
Traceback (most recent call last):
File "c:\python37\lib\runpy.py", line 193, in _run_module_as_main
"__main__", mod_spec)
File "c:\python37\lib\runpy.py", line 85, in _run_code
exec(code, run_globals)
File "C:\Python37\Scripts\nrfutil.exe\__main__.py", line 4, in <module>
File "c:\python37\lib\site-packages\nordicsemi\__main__.py", line 50, in <module>
from nordicsemi.dfu.bl_dfu_sett import BLDFUSettings
ModuleNotFoundError: No module named 'nordicsemi.dfu.bl_dfu_sett'

So it looks like BLDFUSettings is missing?

Python on my machine is version 3.7.3 and nRF UTIL is version 6.1.0

Do you have any idea how I can get around this problem?

Thanks

Just a quick update, I installed Python 3.7.0 on a (clean) PC and then installed NRFUTL and it seem to work.

So maybe 3.7.3 doesn't work, or maybe I need to clean my development PC.

So the question is how do I do that?

Hi Ian, 

You could try re-install  nRF Util  or uninstall https://www.educative.io/edpresso/how-to-uninstall-python and install Python 3.7.0.
