Fix – Dropbox crashes in Windows 10
Solution 1 – Switch off Anti-virus Software
Anti-virus software might be interfering with Dropbox. That’s especially the case if your anti-virus utilities are McAfee VirusScan Enterprise 8.8 and Panda Global Protection. You can disable your anti-virus software as follows.
- Open the Task Manager by right-clicking the taskbar and selecting Task Manager.
- Then click the Processes tab and scroll to your anti-virus utility.
- Next, you should right-click the anti-virus utility and press the End task button.
- If Dropbox no longer crashes with the anti-virus utility temporarily closed, you should then remove the anti-virus software from Windows startup. Click the Start-up tab on Task Manager, select the anti-virus software there and then click Disable.
Solution 2 – Disable TuneUp Utilities and Reinstall Dropbox
If you can’t open Dropbox, do you have the TuneUp Utilities software? TuneUp Utilities is known to uninstall Dropbox as part of its ‘system optimization.’ So you should disable TuneUp Utilities with the Task Manager the same as anti-virus software. Then re-install the Dropbox software.
Even if you don’t have TuneUp, consider reinstalling Dropbox so that it’s the most update version. If the software doesn’t automatically update, you might even get an old version error along the lines of: “You’re using an old version of Dropbox. Please update within the next X days to continue using Dropbox.”
Solution 3 – Reset Dropbox Settings
Fixing corrupted Dropbox settings might just do the trick. You can fix the software’s settings as follows.
- If Dropbox is running, you should close the software by clicking its icon on the system tray and selecting Exit Dropbox.
- Open Run by pressing the Win key + R hotkey.
- Input ‘cmd’ into the Run text box and press Enter to open the Command Prompt.
- Input icacls “%HOMEPATH%\Dropbox” /grant “%USERNAME%”:(F) /T into the Command Prompt and press Enter. If C:\Users\YourUser\Dropbox is not your Dropbox folder location, you should replace “%HOMEPATH%\Dropbox” in the command with your Dropbox folder path.
- Copy and paste icacls “%APPDATA%\Dropbox” /grant “%USERNAME%”:(F) /T into Command Prompt and press Enter.
- Input %LOCALAPPDATA%\Dropbox” /grant “%USERNAME%”:F /T into the Command Prompt and press Enter.
- Finally, enter %PROGRAMFILES%\Dropbox” /grant “%USERNAME%”:F /T in the CP window and press the Return key.
- Then start your Dropbox client software again once the final Command Prompt operation has finished.
Solution 4 – Run the SFC Tool
Are you getting an Error 404 crash while running Dropbox that states, “Error 404: Dropbox has encountered a problem and needs to close. ”? If so, there are probably some faulty Windows system files to fix. SFC (System File Checker) is one of the best Windows Command Prompt tools, and you can fix Dropbox crashes with that as follows.
- Open the Command Prompt as system as admin by pressing the Win key + X and selecting Command Prompt (Admin).
- Enter ‘sfc /scannow’ into the Prompt window and press Return key.
- Then wait the until the SFC tool has fully weaved its magic. When it’s done, you can close the Command Prompt.
Solution 5 – Run the Windows System Restore Tool
If Dropbox has only been crashing more recently with Error 404, consider running the System Restore tool to restore the program back to a time when it wasn’t crashing. This is how you can utilize the Windows System Restore tool.
- Enter ‘system restore’ into the Cortana (or Start menu) search box.
- Select Create a restore point to open the System Properties window.
- Press the System Restore button to open the window directly below.
- Press the Next button on that window.
- Then select the Show more recent points check box.
- Now select a restore point to revert Windows back to. Select a restore point date when Dropbox wasn’t crashing.
- Click Next and then press the Finish button to confirm your system restore point selection.
Solution 6 – Try the UWP version
If you’re having problems with the regular version of Dropbox, go ahead and try the official UWP client. Sure, it may not mean that the UWP version will certainly function better, but we guess it’s better optimized for the Windows 10 environment, so you can give it a try.
You can download the UWP version of Dropbox from the Windows Store for free.
Solution 7 – Run the App Troubleshooter
On the other hand, if the UWP version is the one that gives you nightmares, there’s a viable solution for that, as well. You can use the famous Windows 10 troubleshooting tool.
Here’s how to resolve Dropbox problems using Windows 10’s troubleshooting tool:
- Go to Settings.
- Head over to Updates & Security > Troubleshoot.
- Select Windows Store Apps, and go to Run the Troubleshooter.
- Follow further on-screen instructions and let the process finish.
- Restart your computer.
Solution 8 – Add Dropbox to the Firewall exception list
There’s also a chance that your very own Firewall is actually blocking Dropbox. To find out if that’s the case, you don’t need to disable the Firewall completely. It’s enough to just add Dropbox to the exception list, and your cloud service should function normally.
Here’s how to add Dropbox to the Firewall exception list:
- Go to Search, type firewall, and open Windows Defender Firewall.
- Go to Allow an app or feature through Windows Defender Firewall.
- Scroll down through the list of apps, and find Dropbox.
- Make sure to check both Private and Public.
- Save the changes and restart your computer.
The same thing goes for your antivirus. So, if you still have problems even after whitelisting Dropbox in the Firewall, make sure to do the same in your third-party antivirus.
That’s about it. We certainly hope at least one of these solutions helped you resolve problems with Dropbox in Windows 10. If you have any comments, questions or suggestions, make sure to let us know in the comments down below.
