  <p>Things I've tried:</p>
  <ol>
  <li>Disable firewall and/or antivirus</li>
  <li>Running cmd and PowerShell as administrator</li>
  <li>Restarting my system and deleting caches</li>
  <li>Ran some proxy server command too but it didn't work</li>
  <li>Removing .android file from appdata (wasn't there anyway)</li>
  </ol>
  <pre><code>C:\Windows\system32&gt;sdkmanager --version
  5.0
  </code></pre>
  <p>Environment Variables are working fine, and no Android Studio was previously installed.</p>
  <p>Thanks in advance</p>
