this is the error message I get trying to install Node.js on my PC

CodePudding user response：

Right click Start button > File Explorer > Select This PC in left column and check C:\ drive in right hand column.

How much free space do you have on the C:\ drive?

CodePudding user response：

To install NodeJS on Windows you need to have a minimum of 10 GB free disk space in the C:\\ drive. From your above error picture I see you are getting a not enough disk space error. So you have to free up some space on the C:\\ drive. And if you still get error when you have enough space then you have to run the installation script as administrator.
