title: Printing the installation path of an external app with the winapps module
body: <p><code>winapps</code> module handles installed software.</p>
  <p>Here's a simple example, which looks for an app with name <code>e-Invoicing System</code> and prints it's location.</p>
  <pre><code>import winapps
  
  for app in winapps.list_installed(): # .list_installed() is a generator of InstalledApplication objects
      if app.name == &quot;e-Invoicing System&quot;:
          print(app.install_location)
  </code></pre>
  <p>But this returns <code>None</code> for some reason. Why doesn't the app path &quot;recognized&quot;?</p>
