First up, lets install node.js by visiting http://nodejs.org/

npm install -g less npm install -g yuicompressor
Also on Windows, everything cracks up unless you add a PATH environment variable for the modules. In Control Panel in System, click Advanced System Settings, click Environment Variables and add the node modules folder to the PATH variable, or add it if its not there:
Go to File > Settings, and under the project settings look for File Watchers. Click the green + to add a watcher. Select LESS.

And on linux machines, you can find it elsewhere. I cant remember offhand, but just take note of the output while you are installing it and you wont go far wrong.
