NRFUTIL has issues unpacking a package.

I went through the python files and put an input pause just before the error so I could see if a folder is created and what is in it. It turns out the folder was created but instead of having the files I would expect to see it had a subfolder that then had the files in it. It turns out my package zip somehow got a subfolder in it and thus when unzipped didn't look right to the program. I didn't generate the zip so I was unaware that having the subfolder would make a difference. Thanks to those who replied.

First thing I did was get the latest version executable from https://github.com/NordicSemiconductor/pc-nrfutil/releases. I got the same issue. So I took your advice. I moved the files all over the disk and nothing changed. I then changed the windows environment variable for TEMP and TMP to a location without any '.' and got this. I changed the temp location to C:\TEMP\

C:\>nrfutil.exe -v -v -v -v dfu serial -p COM3 -pkg Driver-v0.3.0.zip

It's the same error just at a different location. I tried running with an admin command prompt as well, just in case it didn't have permissions to write.

It seems the path is the problem, in specific the 'randy.cole is turned into 'randy~1.col'. Try to change the path from where you are running nrfutil.exe.
