Dropbox on Mac not starting after recent upgrade

Hey Malpani, thanks for bringing this to our attention.

Can you please quit the Dropbox app and then relaunch it from your Applications folder, to see if that helps?

already done that. Also uninstalled and reinstalled but the issue is the same. it isn't working and this is the message I am getting.

Hey Malpani, can I send you an email, in order for us to have a closer look into this? 

sure. do you have my email address?

Hey Malpani, yes, I got you! 

I just sent you an email, and I'll see you there. Cheers!

I found people having an issue with a similar error message, but mine doesn't mention permissions. That said, in the .txt file, the final line says "Permission denied".

Basically I've completely removed (via the advanced reinstall) Dropbox and re-installed it and am still getting the same error message after logging the Mac Desktop App into my account. 

The message reads the following:

Couldn't start Dropbox.

This may be a temporary error. Please restart Dropbox.

And then there's a .txt file with the following content:

Any help or ideas would really be appreciated

Hi cleversam, sorry to hear about that! 

You mentioned you've already performed the steps to an advanced re-install. In that case, can I send you an email in order for us to have a closer look into this? 

Keep me posted! 

sure as my problem hasn't been solved a yet.

Hey Malpani, I just reached out to you, so we'll continue via email!
