Meteor command not found -

I have installed the same version from a computer and the command "meteor" runs normally, now I have another computer Trying to install in me but giving me the issue that "Meteor command was not found" I tried to add the path to the system variable, but it does not seem to work. any idea? You have discovered in Windows (using Windows 8.1) that you have to type the meteor.
