I encountered the same issue and solved it as follows:
- Uninstall “NVM for Windows 1.1.7”
- Run the installer
nvm-setup.exeas Administrator -
Open an elevated Command Prompt (with Administrator privileges) and run
nvm install 8.12.0nvm use 8.12.0
Now running node -v in a non-elevated Command Prompt works without issue. Hope this helps!
