"Installation failed. The Dropbox installation failed to start" error on Windows 11

Dropbox has worked fine for many years on my Lenovo Thinkpad X1, then suddenly stopped working. The link on the start menu became inactive. Starting Dropbox from dropbox.exe directly said the installation was corrupt.

I have downloaded the Installer and the Off-line installer and both give the message "Installation failed. The Dropbox installation failed to start".

Turning off the Microsoft Firewall and Anti-Virus makes no difference. There is no VPN installed. Window 11 has all the updates. Also I have uninstalled Dropbox from my computer and tried to reinstall, again the Dropbox installation will not start. At each stage my computer has been rebooted.

My datafile to which Dropbox is attached remains intact.

It seems I not the only person suffering this problem, but no final solution seems to be offered. I wondered about searching my registry to delete any references to Dropbox.

Can anyone suggest a solution?

    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.

    Hey folder, hope you don’t mind if I jump in here. You don’t happen to use Windows 11 in S mode, correct?

    I do not think so. It is Windows 11 Pro 24H2.

    Hey folder, let me also jump in here! 

    Do you get the error on the screenshot, right when you're about to run the .exe file? 

    In any case, can I send you an email, in order for us to have a closer look into this?

    Windows asks if I want the program to make changes to the computer. Answer yes and the message dropbox installer failed to start appears.
