To run a node.js program, if I copy only the node binary, then I am seeing that it is working fine. Just wanted to know if I do not install node.js, only copy the node binary in the bin directory, is there any chance that it may not work properly.
On linux or mac, this should be fine. On windows, I don't know.
For Windows, your best bet for stability is to download the binary directly at http://nodejs.org/download/. Look for Windows Binary (.exe). It will run without installation. This, of course, will not include npm.
