If you don’t see the Open button when viewing files on dropbox.com, try troubleshooting the following issues.
Does your computer meet the system requirements?
The Open button requires:
- A supported operating system
- A supported web browser (Chrome or Firefox)
- The latest version of the Dropbox desktop app
Is the Dropbox desktop app running on your computer?
The Open button requires that the Dropbox desktop app is running on your computer. To see if the app is running, look for the Dropbox icon in your computer's taskbar (Windows) or menu bar (Mac). If it’s not running, you can open it just like any other app on your computer—through the Windows Start menu or the macOS Launchpad.
Are ports 17600 and 17603 available?
The Open button requires that the Dropbox desktop app have access to ports 17600 and 17603. If a firewall or antivirus app is preventing Dropbox from using one or both of these ports, you may need to configure the firewall or antivirus app to allow Dropbox access to these ports.
Are you signed into the correct account?
The Open button requires that you're signed into the same Dropbox account on both dropbox.com and the Dropbox desktop app.
Is the link pointing to a file in your Dropbox account?
The Open button appears only for files already synced with your computer's local Dropbox folder. To see if a file exists in your local Dropbox folder, look for it in File Explorer (Windows), Finder (Mac), or the Dropbox desktop app.
