Can't start Dropbox on my PC

[BBN]

I've never had any issues with Dropbox until now. I started my PC tonight and it told me it couldn't start Dropbox. I tried restarting my computer but that didn't help. I have not made any changes or updates to my computer and I'm the only one who uses my PC.

This is what it told me:

If you're talk about Dropbox desktop apps. it is service and function are all terminate on january 17 2022.
so you can only use file explorer or finder of mac

Hi @BBN, I hope you're doing well! 

Can you try following the steps in order to perform an advanced re-install on your end? 

Let me know how it goes!

[ThomasCarruth]

I am having the exact same problem on Windows 10.  I have performed the Advanced Reinstall multiple times.

This happens when using my regular Microsoft account on my laptop.

Presuming something was corrupt under that user, I then used my local account on the laptop, which I never run programs from and decided to try and start Dropbox.exe, which did then start.  I then signed-in with my regular Dropbox credentials and everything synced.
***This however is not an acceptable solution because I need my Dropbox files under my regular Microsoft account on my laptop.***

!!!This does prove that the root of the problem lies with the Dropbox data associated with my regular Microsoft account on my laptop!!!

I tried renaming the Dropbox folder hoping that would trigger a re-signin and synch but nope.

Now that someone else is experiencing the same problem, it is apparently a problem with release 140.4.1951.

We have restarted the computer, uninstalled and reinstalled dropbox off the computer. If anyone knows how to fix this it would be much appreciated!!

Hi @megatron1003, let's jump right into this! 

Can you perform an advanced re-install for your device, and let me know how it goes? 

Keep me posted!
