Troubleshooting for failed installation of the Dropbox app on your computer

  • Make sure your antivirus software or firewall isn’t blocking the installation
    • If it is, you can manually configure your firewall to work with Dropbox using this guide
    • If you see a “Cannot establish a secure connection” error message, follow this guide
  • Make sure your computer meets the minimum system requirements to run the Dropbox app
  • Make sure you’re installing the latest version of the Dropbox app
  • If you’re trying to run Dropbox on a corporate network (a company’s WiFi), make sure it’s supported 
  • If you’re using a Dropbox Business account, contact your team admin and make sure they’ve approved your device for installation

Note: If you’re not the administrator on the Mac computer you’re trying to install Dropbox on, and you’ve tried these troubleshooting steps, you may need to install manually.

Why can’t I use Dropbox on a corporate network?

The Dropbox app may not install or sync on corporate networks. If you’re not sure if Dropbox is supported on your corporate network, contact your company's network administrator to find out.

Some corporate networks are behind HTTP proxy servers that use NTLM authentication. Dropbox currently doesn't support this kind of proxy authentication. However, some users have reported some success using an intermediate proxy, such as NTLMAPS or cntlm, to get Dropbox running on their network.
