Dropbox won't start

[zzzz3]

I installed dropbox on a new pc. It was working but after I uninstalled the default antivirus it just never started again. So I uninstalled and installed several times. When I finish the installation I always get the same message.

Couldn't start Dropbox. 

Here's the log of the error:

Hi @zzzz3,

You can try delete the folder C:\Users\gonsa\AppData\Local\Dropbox and sign in your application anew. Take in mind that all local preferences will reset and you may set them anew if desirable.

Good luck.
