title: 'cfx' is not recognized as internal or external command
body: <p>I was actually developing an add-on with the Add-on Builder but now I would like to change to SDK since there are more possibilities.<br>
  I have installed the sdk and Python like so: 
  C:\Users\bla\Add-ons\addon-sdk-1.8.1<br>
  (inside addon-sdk-1.8.1 I added the tar Python-2.6.8)<br>
  Now in the cmd I typed:  </p>
  
  <pre><code>cd C:\Users\bla\Add-ons\addon-sdk-1.8.1  
  mkdir my-addon  
  cd my-addon  
  cfx init  
  </code></pre>
  
  <p>That worked fine -> the folder my-addon has been created with the whole directory in it.<br>
  Then I deleted the folder my-addon and tried the same commands again and got: </p>
  
  <pre><code>'cfx' is not recognized as internal or external command, 
  operable program or batch file.   
  </code></pre>
  
  <p><code>mddir my-addon</code> created the folder my-addon. But <code>cfx init</code> produced the error. </p>
  
  <p>It's the first time I'm working with cmd commands and I have no clue what I gotta do now</p>
