Dropbox App won't open, the only thing that opens is my Dropbox Folder.

Yes. There is no dropbox  icon in the system tray. 

Hey Uitlander - sorry to jump in here, but I can see the Dropbox desktop app's icon in your system tray. It's the one with the red "3" showing. 

Have you tried clicking on that?

I am also having the same problem.  Started about 8 months ago.  Very frustrating.  First the icon disappeared after a short time and now after reinstalling and trying everything you have listed above, I never get the icon so can't update sync options. 

Hey swright4 - sorry to hear you're still having issues with this.

Could you clarify your device's OS version and let us know if you've tried the offline installer from this page directly? 

I have the same issue in macOS.

Can't open the app. It only opens the folder. Can't right click on files to copy url. No Dropbox options when right clicking Dropbox files.

Hey Pookeyblow. From what I understand, you’re not seeing the Dropbox icon in your menu bar and the desktop app isn’t running/syncing, correct? 

If you open your Finder > Applications folder and double click on the Dropbox app from there, do you see the Dropbox icon again after a few seconds, along with the Dropbox options in your context menu?

wrong, something must really be one about all the problems on these online support forums, and the wrong advice given.

there is no drop box desktop app, it only opens the file explorer

Thanks for the tip, Rich. It was driving me crazy. I know it's an old thread, but putting a note here if it helps anyone, if closing and relaunching doesn't work, kill all instances of Dropbox from Task Manager and then try to reopen. That's what finally worked for me.
