Hi @Aash9

What command are you running when you get that error?

Try restarting computer to relase any locks / kill any hung processes

ALSO: delete the folder `C:\Users\Administrator\AppData\Roaming\npm\node_modules\windows-build-tools` (or at least delete the file/folder `C:\Users\Administrator\AppData\Roaming\npm\node_modules.windows-build-tools.DELETE`)

ALSO: make sure you run the installation command in an elevated command prompt (right click `cmd`, run as administrator)

Lastly, it can take a loooooong time (30mins plus) - wait it out.

See npm page for more info: [windows-build-tools - npm](https://www.npmjs.com/package/windows-build-tools)
