"This file does not have an app associated with it for performing this action."
Dropbox Desktop App installs fine on my Win 11 PC. Unfortunately, I'm unable to sign in to it. The error message reads:

This error usually means Windows isn’t handling the dropbox-client:// URL protocol correctly, so the OAuth sign-in can’t complete. It’s a known issue on some Windows 11 setups after clean installs or updates. A common fix is to fully uninstall Dropbox, reboot, then reinstall using the offline installer as administrator, which often re-registers the protocol properly. Also check Settings → Apps → Default apps → Choose defaults by link type and confirm the dropbox-client protocol is associated with Dropbox. If it still fails, temporarily disabling browser extensions or trying a different default browser for the sign-in step can also help.
