Hi, Dear Nordic & all:

  when I prepare to do a DFU example，I get trouble in installing "nrfutil" tool 

  I sure that I installed it successfully， but when I input "nrfutil version" to check its version , It returned innormal result just like below:

normal result is just like this:

So, what's reason for this?

Thanks for your kind reply and suppport!

Hi, 

It sounds like the Colorama environment issue if you search for the error message "module 'colorama' has no attribute 'AnsiToWin32' ". 

Try to install colorama · PyPI. If it still cannot fix the issue, you might need to seek help on https://stackoverflow.com/
