Unable to complete installation. Installation is performed on Windows 10. Error text: (Installation failed due to unknown error (Error code: 1).
I installed autoload from the site, installed the ofline version, installed the old ofline version, turned off the antivirus, turned off the firewall - the same error.
Help install the application. Please do not write, dear moderators, messages about reinstalling without antivirus, installing with the removal of previous versions, I did everything. Are there any new ideas that have not been written about in the following discussions:

The solution turned out to be funny, but not very. Simply, if you have another computer or laptop, and dropbox is working there, then copy the Program Files(x86) folder from your another computer to yours. I just installed win 11 on the ****** drive without deleting the old system- win 10, and installed dropbox in win11 and then just copied it to win10 and everything worked. If there is the same error, but there is no way to get the files, then you can write here and ask for dropbox files... I'll send it, but I won't see the message right away.
