If you don’t see the Open button when viewing files on dropbox.com, try troubleshooting the following issues.
Is the link pointing to a file in your Dropbox account?
The Open button will only appear 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.
Is the Dropbox desktop app running on your computer?
The following must be true for the Open button to appear:
- The Dropbox app must be running on your computer
- You must be signed in to the same account on both dropbox.com and the desktop app
Does your computer meet the system requirements?
The following are required to see the Open button:
- A supported operating system
- The latest version of the Dropbox desktop app
- A supported web browser:
Are you signed into the correct account?
Double-check that you've signed in to the same Dropbox account on both dropbox.com and the Dropbox desktop app.
Are ports 17600 and 17603 available?
The Open button requires that the Dropbox desktop app have access to ports 17600 and 17603. It's possible that a firewall or antivirus application may be preventing Dropbox from using one or both of these ports. If this is the case, you may need to configure your firewall or antivirus app to allow Dropbox access to these ports.
