Look in a verbose log for specifics rather than guessing but: 1. Obviously, lack of any actual files in use that need upgrading, subject to version rules and where you have sequenced RemoveExistingProducts.
2. OS versions with Restart Manager have improved uninstall behavior. They tend not to prompt files in use because the OS remaps it, removes the disk copy, and at the next reboot (or the user shuts down the app) it's gone. 3. Other scenarios (like apps that integrate with Restart Manager) that avoid explicit in use dialogs.

I posted this in a wrong subgroup so I am posting it again.
