The Dropbox app is not launching. "Dropbox has unexpectedly quit." error.

[H. Hanyang]

"I'm using Windows 10 Pro and since late August, I've been getting a message saying, "Dropbox has unexpectedly quit. Please restart." When I uninstall and reinstall the Dropbox app, it works fine until I reboot my PC. After rebooting, the message appears again and the app doesn't start or sync. Dropbox stops working after every reboot."

Hello @H. Hanyang - welcome to the Dropbox Community!

I'm sorry to hear you're having issues with our desktop app on your computer. Have you already tried performing an advanced reinstall? 

While we're at it, what's the exact OS and Dropbox version that your device is using and approximately how many files are you trying to sync via the desktop app?

Thanks in advance!

[H. Hanyang]

My Windows version is Windows 10 Pro 22H2, and my Dropbox version is v207.4.35821. The number of shared files is unknown, but the total shared file size is approximately 330GB.

Hi @H. Hanyang, did you have the chance to check the advanced re-installation process, and perform it on the device? 

[H. Hanyang]

I've tried an advanced reinstallation, completely removing and reinstalling the software, but the problem remains. I suspect it might be conflicting with Adobe Creative Cloud. Dropbox, which has worked flawlessly for 10 years, is now malfunctioning. I'm at a loss as to what to do next. If I can't find a solution, I'll have to explore other cloud storage options.

Hey @H. Hanyang - could you try the latest, stable version of the app from this page directly and let us know how it goes?

If the issue persists, you can try creating a new OS profile and installing the app there as a test. 

Keep us posted anyhow.

I have completely uninstalled the Dropbox app and reinstalled version 208.4.5824 using the provided link. However, Dropbox only runs immediately after installation. Upon rebooting, I consistently encounter the error message "Dropbox has unexpectedly quit," preventing the app from launching or synchronizing. During the reboot process, the Dropbox icon appears on the taskbar a couple of times before disappearing, followed by the error message.

I suspect that this issue might be related to a conflict with Adobe Creative Cloud, as both applications provide cloud storage services. Although our company has used both Adobe and Dropbox products on two PCs for the past 10 years without any problems, both machines have started experiencing this exact issue simultaneously.

Please note that both Adobe Creative Cloud and Dropbox (version 208.4.5824) are fully updated. I'm concerned that if Dropbox cannot provide a solution, we may need to explore alternative cloud storage options.

Does the issue persist when you temporarily close the Adobe app completely @H. Hanyang?

[H. Hanyang]

I've tried deactivating all running Adobe-related apps in the background, but the issue persists. Yesterday, when an Adobe PDF update ran, Dropbox temporarily started and synchronization worked. However, after restarting Windows, Dropbox is not starting again.

Thanks for the additional details @H. Hanyang 

Can you maybe try creating a new OS profile on your computer with admin privileges and try to install the Dropbox desktop app there, and let us know if the issue crops up again?
