title: How to execute a command from a certain directory in Inno Setup script
body: <p>I have multiple <code>cmd</code> commands which is about installing <code>npm</code> components. I don't want to use batch file for this purpose. How can I execute these commands through <code>Exec</code> function in an Inno Sectum script and I want the installer to wait until these commands get executed?</p>
  
  <p>Here are some example commands I wish to execute also they need to be executed on specified directory:</p>
  
  <pre><code>npm install forever-monitor
  npm install ip
  </code></pre>
