What to do if the Dropbox desktop app won't install

If the Dropbox app on your computer won’t install, the simplest solution is to try downloading the full installation instead of the regular installation. They both install the Dropbox app, but the full installation doesn’t require an internet connection.

Troubleshooting for failed installation of the Dropbox desktop app

☑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.
• Follow our help center guide if you see a “Cannot establish a secure connection” error message.

☑Make sure your computer meets the minimum system requirements to run the Dropbox desktop app.

☑Make sure you’re installing the latest version of the Dropbox desktop app.

• Find and install the latest version of the Dropbox app for your devices or operating system.

☑If you’re trying to run Dropbox on a corporate network (your organization’s Wi-Fi), make sure it’s supported.

☑If you’re using a Dropbox team account, contact your team admin and make sure they’ve approved your device for installation.

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

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

Some corporate networks are behind HTTP proxy servers that use NTLM authentication, which Dropbox currently doesn't support. However, some users have been able to use an intermediate proxy, such as NTLMAPS or cntlm, to run Dropbox on their network.
