Dropbox application suddenly not working with Windows 11

[PDub81]

Yesterday, I noticed that Dropbox was no longer connected on my laptop running Windows 11.  There is no system tray icon for Dropbox, and clicking on the start menu app icon does nothing at all; same for "Open Dropbox" on the website.  I've uninstalled, reinstalled, rebooted multiple times, tried different firewall settings, redownloaded the installer, but no luck with anything.  A previous thread discusses a similar problem, but no solution:

Unfortunately this problem has occurred again.  I need suggestions for a permanent solution.  I don't want to be stuck reinstalling every few weeks.

Hey @PDub81, I’m sorry to hear the issue’s back. 

If you want, I can open a support ticket for you and investigate this further. 

Let me know if that’s alright.

[PDub81]

Hi Nancy, yes please!

[Nancy]

You’re all set! I’ve logged a ticket for you, so that we can check this together. 

Please reply back to me, when you’ve got some free time. 

Cheers!

Nancy, I have been out of town and away from the computer in question, which I did not want to post on a public forum beforehand.  I am now back home.  Please reopen the support ticket.

Hi @PDub81, I've sent you an email, please could you reply to it as soon as possible!

Same problem ... offline installer does not work.  It does not automatically run (I think) but when I click on "restart the download" I get the following:

I should add that I've tried every suggestion that I've seen.  All of a sudden stopped syncing (maybe after a recent Windows update, but not entirely sure).

Hey @pafnooty, sorry to see you're having an issue with the Dropbox desktop app.

Are you also not seeing the Dropbox icon in your system tray?

If you see it, can you please hover over it with your mouse, to see the app's sync status?

[PDub81]

Sorry, pafnooty.  Have you tried switching user accounts on the computer and reinstalling on the other account?  It hasn't happened to me again, but I also received a message that it could be related to security or firewall settings.  Good luck!
