NPM cant find module, win 7/64 bit

I just have installed node for windows 64 bit with the msi installer from node.js site, on windows 7 64 bit. It sad that it install node path and npm(node package manager). And when I type node in CMD it goes to interactive console and I can run .js scripts with it(it's working). But when I type npm I get this error. I did not change any paths and it's a fresh install.

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\npm\bin\node_modules\npm\bin\npm-cli.js'
