The app restarts and keeps asking for my credentials, even after signing in.

Hey there, xfilesphan​, welcome to our Community! 

The first thing I'd personally check would be your antivirus.

I suggest temporarily disabling any antivirus or security programs on your computer, and reinstalling the Dropbox application using our offline installer.

Also, do you, by any chance, have roaming profiles implemented or has your C drive or the locations where Dropbox folder will live (like your home directory or any of the folders within it) shared over a network drive?

The description you've provided seems to indicate that this may be the case, which is most likely the reason for the failure. Currently, installing Dropbox on either a shared folder or network drive, using redirected folders are not supported.

I’d recommend asking your IT administrator for more information about these types of setups, or to request them to stop the %APPDATA% folder from roaming.

If you have used redirected folders to change the location of the Dropbox install, we recommend reinstalling Dropbox and allowing it to install to the default locations.

Let me know more, and we'll take it from there!

Hi,
We can test the antivirus, but I have an identical machine (same model, same image, including security suite) that functions normally. We downloaded and installed using the latest stable offline installer package.

We do not use roaming profiles. This is a local folder in c:\users\user-name\dropbox. We do not redirect folders or install pointing to a network location.

It is just this instance from what I can tell. The behavior persists, but what is odd is that even with an uninstall of the product, the system seems to recognize the login following a reinstall. This makes me wonder if there was a way to confirm a clean uninstall. Would we need to clear browser cache - since the browser is involved in the logon process?

Hey xfilesphan​!

Since you made sure that you haven't implemented any roaming profiles, then I would suggest what you already mentioned, which is to clear your browser's cache after disabling your antivirus too. 

I know that you might have the exact same set-up on a similar device, but sometimes each device's unique configuration plays an important role too. 

If that doesn't work either, let me know and we'll proceed with the next steps.

Awesome news xfilesphan! 🤓
