    I had the same error:

    Installation failed. The Dropbox installation failed to start.

    I also could not run Dropbox nor uninstall it!
    I asked ChatGPT to troubleshoot with me. After spending an hour cleaning registries, folders, repairing, safe-mode, etc. I then tried running the standalone installer from the command prompt with a flag to try and view log output. I started my command prompt and navigated to the location of my installer exe, then ran:

    "Dropbox 228.4.5567 Offline Installer.x64.exe" /log DropboxInstallLog.txt

    This failed even sooner but at least produced an error code 0x80040c01.

    ChatGPT realized this may be an issue with Google Update components. It suggested doing a silent install with the /S flag:

    "Dropbox 228.4.5567 Offline Installer.x64.exe" /S

    And this worked immediately!

Hey folder - sorry to hear you're having issues with this.

Could you please try an advanced reinstall using the offline installer from this page directly and let me know how it goes?

If you still get the same error, please send me a screenshot as well!

Thanks!

    Can you explain how to "If you use selective sync, take note of the preferences you applied."? How is it done when Dropbox has stopped running?

      Hey folder, I'm afraid that if the app is not running, you won't be able to see your selective sync settings.

      Does the advanced reinstall help otherwise?

        There has not been an answer to why stable build 222.4.5042 produces either:

        OR the same installation error reported in the start of this thread.
