Installing Ember.js 2.2

I tried do install Ember.js v2.2 by following the official instructions: http://ift.tt/1OOJL3l

• installed Node.js and npm
• installed Git
• installed the Ember CLI via npm install -g ember-cli

Everything should be fine now.

But when I type ember -v to verify the Ember version, it says: 1.13.13 I did follow the 2.2 Instructions to the point, but I didn't get Ember.js 2.2 installed.

Any suggestions? I use Win 7.
