Can't start Dropbox

I'm getting an error message that Dropbox can't start on my Mac (running macOS Monterey). I tried an advanced reinstall of Dropbox to no avail. Here's the error text. Any help would be so appreciated!

Worked like a charm! Thank you, Megan!

Great news, @Dan47!

If you need anything, I'll be one post away.

Apologies in advance - I have so little experience with computer stuff that I'm not even sure which board this should go on. I recently moved from a Dell laptop tp a MacBook Air. I signed into dropbox on the Mac and could see all my files so thought I was good to go. Discovered today that others who use my shared folders can't see the docs I've added.

I usually go to Finder and access my dropbox there. When I click on the dropbox icon in the taskbar I get this message:

Screen Shot 2022-02-06 at 4.40.26 pm.png

When I click OK the window vanishes. When I click on the link I get a box of data I don't understand.

Not sure what to do or where to go from here?

Ho installato Dropbox sul mio MacOs versione 12.1, all'avvio di Dropbox mi compare questo messaggio:

Impossibile avviare Dropbox

Solitamente questo problema è dovuto a un errore nelle autorizzazioni.

Anche l'archiviazione della cartella home in un percorso condiviso di rete può provocare errore.

Come posso risolvere questo problema?

Non capisco perchè parli di autorizzazione, il computer che sto usando è solo mio e contiene solo un account amministratore, non ci sono altri tipi di account.

Megan

Ehi @Dan47 p & @michele_b99 , sarei felice di aiutarti!

Puoi fare clic sul collegamento ipertestuale blu e inviarmi il registro degli errori completo, così posso analizzarlo e inviarti i passaggi successivi?

Se la tua app non si aggiorna, è per questo che gli altri non vedono le tue modifiche. Modifichi i file utilizzando l'app desktop o il sito Web?

Grazie mille.

PS: ho incluso una versione tradotta automaticamente della mia risposta, per @michele_b99. Ci scusiamo per eventuali errori che potresti trovare.

Hey @noobneedshelp & @michele_b99, I'd be happy to help!

Can you click on the blue hyperlink, and send me the full error log, so I can analyze it and send you the next steps?

If your app isn't updating, that could be why others don't see your changes. Do you edit the files using the desktop app, or website?

Thanks a bunch.

PS: I've included an automatically translated version of my response, for @michele_b99. Apologies for any mistakes you might find.

Ciao @AdeleFab, spero che tu stia bene!

Se non hai un account Basic gratuito con più di 3 dispositivi collegati, puoi provare invece una reinstallazione avanzata e farmi sapere se il problema è stato risolto?

Fammi sapere come va.

-------------

Hi @AdeleFab, hope you’re doing well!

If you’re not on a free Basic account with more than 3 devices linked, can you try an
advanced reinstall instead, and let me know if the issue is resolved?

Let me know how this goes.

AdeleFab

Io ho un account basic con 3 dispositivi connessi.

Ho provato a fare una reainstallazione ma continua a comparire lo stesso msg di errore.

PS. cosa intendi per reinstallazione avanzata?

Scusa il ritardo ma non avevo ricevuto la notifica della tua risposta, anzi grazie.

Adele

giuliavargiu

Buonasera, qualcuno può aiutarmi? Ho installato dropbox su windows11 ma non riesco ad avviarlo.....come posso risolvere? Non mi compare nessun messaggio di errore, lo vedo fra le applicazioni ma poi non si apre.

Fino ad un paio di giorni fa funzionava, poi è comparso questo simbolo (sembra una scatolina marrone) accanto ai file e non sono più riuscita nè ad aprire nè a sincronizzare i file su dropbox. Quindi l'ho disinstallato e reinstallato ma niente 😕 simbolo dorpbox.jpg

Megan

Ciao @AdeleFab e @giuliavargiu!

Suggerirei di seguire entrambi questi passaggi per eseguire una reinstallazione avanzata del dispositivo.

Inoltre, Giulia, l'icona che hai postato sopra non sembra essere correlata a Dropbox. Forse hai altre app di terze parti sul tuo dispositivo?

Tienimi aggiornato sui risultati.

---

Hi there, @AdeleFab & @giuliavargiu!

I'd suggest that you both follow these steps in order to perform an
advanced re-install of the device.

Also, Giulia, the icon you posted above doesn't seem to be a Dropbox related one. Maybe you have any other third-party apps on your device?

Keep me posted on the results.

Quella non è un'icona Dropbox. È da Microsoft OneDrive. Probabilmente hai onedrive e Dropbox cercando di sincronizzare gli stessi file e stanno interferendo tra loro. Non è una buona idea avere due servizi di sincronizzazione che sincronizzano gli stessi file.

AdeleFab

Carissima,

ho provato la reinstallazione avanzata ma non è cambiato nulla ahimè

😞

continua a comparire il messaggio di errore con quanto segue:

Ciao @AdeleFab!

Andrebbe bene se ti contattassi via e-mail in modo da poter approfondire ulteriormente la questione?

----

Hi @AdeleFab!

Would it be okay for me to reach out via email, in order for us to have a closer look into this?

AdeleFab

Assolutamente si,
Anzi grazie mille

Megan

Nessun problema, @AdeleFab!

Ti ho appena inviato un'e-mail così possiamo dare un'occhiata più da vicino a questo insieme.

Ci vediamo lì!

No worries, @AdeleFab!

I just sent you an email so we can have a closer look into this together.

See you there!
