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

"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."

I was able to fix the problem by swapping out the router for a new one.

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.

Walter

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?

H. Hanyang

관리자 권한으로 새 계정을 만들어야 한다는 요구 사항은 두 계정을 관리하도록 강요하는데, 이는 매우 비효율적이고 짜증나는 과정입니다. 다른 클라우드 서비스로 전환하는 것이 훨씬 더 현명할 것입니다. 저는 Dropbox의 현재 제한 사항에 매우 실망했습니다.

Hello @H. Hanyang

Maybe I can help with this. Could you please send a screenshot of the error message "Dropbox has unexpectedly quit" to see how it looks visually? That could be a helpful indicator of what to do next.

Thanks,

I'm Korean. The error message is also in Korean. I've attached a screenshot.

The error message means the following

Dropbox has crashed unexpectedly.
Your files are secure. Please restart Dropbox to resume syncing and other functions.

@H. Hanyang, regarding your previous post, keep in mind that Walter’s previous suggestion to set up a new user profile on your computer with admin rights is purely for troubleshooting reasons and we don’t expect you to have a separate profile to run the Dropbox app.

If you try this step though and it doesn’t help or if you can’t test this, let us know and we’ll further assist.

DBoxTips

Thank you for the details @H. Hanyang. That is helpful because it means that Dropbox is crashing internally due to a known reason, as opposed to an external startup crash. I can help with further troubleshooting this for you or Dropbox support could assist you if you open a ticket.

I noticed the moderators removed part of my post “due to Community Guidelines”. Moderators, I genuinely want to understand what specific community guidelines were enforced here, since I just posted an offer to help free of charge, no strings attached, nothing promotional or commercial.

Hey @woong! Have you also tried uninstalling and reinstalling the Dropbox app and the issue persists?

woong

삭제하고 설치후에도 문제가 지속되고있습니다. advanced reinstall 을 해도 계속 지속지속중입니다.

It works during indexing and shuts down the program when synchronization starts.
