After cleaning up everything I installed a new v1.4.1 using nRF Connect Desktop - full version not http://developer.nordicsemi.com/.pc-tools/toolchain/ncs-toolchain-v1.4.1-20201215-7ecf886-minimal.zip ( Does it matter other than the time to install?). I did the west update then went to move newtmgr.exe when I notice the path you suggest doesn’t exist. The env.cmd that nRF Connect installed sets the path to tcdir which is (I setup ncs on D: dirve) D:\ncs\v1.4.1\toolchain; the main program folder is:
For windows they have moved most everything into D:\ncs\v1.4.1\toolchain\opt\bin
D:\ncs\v1.4.1\toolchain\bin is not in the path.
If I run bash from D:\ncs\v1.4.1\toolchain\bin it sets up the bash environment for nRF.
The Windows CMD version D:\ncs\v1.4.1\toolchain\cmd\env.cmd will setup the environment for Windows COMMAND PROCESSOR not PowerShell.
You have to run bash or env.cmd to setup the environment for nRF.
I have ncs at the root of D:
Will setup a Windows for nRF.
