Installation fails near the end even after trying a different directory. How can I tell whether an old process or the installer is involved?
This answer refers to the version in the original report. Check the controls and behavior in your own version.
The percentage identifies a stage. Save work, quit the old Desktop app and its Harness host normally, then check Task Manager for processes that remain.
Record the installer version, architecture, fresh-install versus upgrade status, and first error before retrying. If the log names a locked file, identify the process holding it. The thread reports mixed outcomes and does not establish a single cause.
