open a new command window after verifying 1 and 2.add a new variable NVM_HOME to the system variables.update the system path variable to the directory where you installed nvm and where the nvm.exe is located.There is no need to uninstall prior versions of node as far as i can tell. So after installation just check that points 1 and 2 are covered and you should be good. There are two things required to get nvm-win to work and the installer only does the first of these two. After installation I got the error that most folks complained about which is that it was unable to find the file settings.txt. I installed nvm-windows in order to get multiple versions of node to work. I dont know if this is the best way, but it worked for me. Probably you will be installing multiple versions, so repeat as needed. From within the admin level command prompt, run "nvm install 7.2.1", or whatever node version you want to install.Open a CMD prompt (run as administrator), and install the downloaded version of nvm, nvm-setup.exe, from within this CMD command prompt.Download your desired version of nvm ( ).Delete the existence of nvm (C:\Users\xxx\AppData\Roaming\nvm), basically, manually delete the nvm dir.To the point where there is no more "nodejs" directory at all. Delete/remove/uninstall the version of node in your "C:\Program Files\nodejs" directory.
Ok, so here is what I did to fix the situation where "nvm use. It seems that nvm is simply switching the shortcut, when we call "nvm use. In the end, this "C:\Program Files\nodejs" directory will actually be a shortcut to where nvm manages the versions it installs (see C:\Users\xxx\AppData\Roaming\nvm). Most of us already have a "nodejs" directory from a prior install, before we decided (or were told) to install nvm. First examine your actual "C:\Program Files\nodejs" directory.
