Won't connect/start up

[Michael L.38]

Same problem with me.  I tried everything, but still no connect, no sync.  So... I copied all of my files over to One Drive (MS Office 365).  Sad to see it go, I was a Dropbox loyalist, but I can't spend all of my time trying to solve their syncing problem.  One Drive is free (1 terabyte) with my annual $100 subscription to office 365, and I get all of MS Office programs for 5 computers.

I'm having all the same problems as listed above. Tried all the canned solutions. Nothing works. turned off all virus checkers completely. Tried to install previous versions, which at least gave me the option to sign into my account, but I was always forced back to 3.8.8 and it just sits "connecting" and doing nothing. Just upgraded to Pro account - what a waste.

Doesn't seem to want to get past Settings menu. Help

Guys I was able to resolve this issue on my own, Dropbox support (even the paid support) was no help what so ever. I will put the steps I took to resolve this below. These are the steps that worked for me, I am not responsible for any data loss if you attempt to use the steps below. 

1. I saved a local copy of everything in my Dropbox to my desktop
2. Uninstalled Dropbox while logged in as the main user profile that was affected using control panel programs and features, also uninstalled Dropbox setup (may not exist for some of you)
3. Deleted the Dropbox folder from my (the affected) user profile and from any other users profiles. Its located here: C:\Users\YourUserName\Dropbox
4. Deleted all Dropbox folders from subfolders in the AppData folder here: C:\Users\YourUserName\AppData Local, LocalLow and Roaming and deleted the Dropbox folders from there. Also do this for the other user profiles on the computer. 
5. Went into regedit and deleted anything named Dropbox (the program doesn't exist anymore so removing these files shouldnt harm anything and the install should replace these files)
6. Deleted Dropbox folder from C:\Program Files(x86)\ (if uninstaller doesn't delete)
7. Created a new user by right clicking on computer > manage > Local Users and Groups > added a new user named dropbox (only temporary) added that user to the Local Administrator Group
8. Rebooted computer and logged into the temporary dropbox user
9. Downloaded and installed Dropbox, made sure the "login" window came up asking for email and password (this was huge, this window wouldn't come up for me when simply uninstalling and reinstalling on the affected profile)
10. Went to switch user, logged in as my primary user account
11. Opened up Dropbox (didn't auto launch) the login window came up!
12. Put in my credentials and Dropbox successfully launched! 

UPDATE: I have now successfully used the above steps on 3 other computers and resolved the issue on all 3, I hope this works for everyone having the same issue! No clue what caused it in the first place...

Thank you Joshua F for the solution.  Seems that Dropbox has "dropped the ball", and instead of their staff fixing the problem, smart guys like you have to do their work for them. I am just a slow-witted financial entrepreneur, mergers and acquisition specialist.  I was hoping that I would not have to get a new part-time job solving Drobbox technical issues.

If any of you are still having problems I solved it by going to Dropbox preferences, navigating to network and then selecting the proxies button. I then selected 'No Proxy' instead of  the default 'Auto-detect'. Then click 'update' and all was fixed!

Dropbox preferences, select the proxies button. Then select 'No Proxy' instead of  the default 'Auto-detect'. Then click "Apply" and Ok, then reset the program.

Will try some of the solutions listed above, but still having issues on windows 10.

That's what helped me. Thanks John R.61.
