    Der SChwule Bill, I moved your post here from the "System File Error" when installing 4.0 thread because your issue seems to be a little different.

    Pfeil Solution to "Setup is unable to validate installation" message


    I had the same problem, this solution worked for me:
    1. Power on your computer.
    2. Press F8 to show safe boot options, choose Debugging Mode and press enter.
    3. Discard all (mainly Deamon Tools) error messages.
    4. Rename the \WINDOWS\System32\Drivers\dtscsi.sys file in whatever you want (to avoid its loading).
    5. Restart Windows in normal mode.
    6. Discard all (mainly Deamon Tools) error messages again.
    7. Put the \WINDOWS\System32\Drivers\dtscsi.sys renamed file to recycle box.
    8. You should now be able to uninstall Deamon Tools.
    9. Reboot once, Daemon Tools has been now correctly uninstalled.
    10. You can reinstall Daemon Tools latest version.
