MSI uninstall doesn't delete some files

Question

I'm creating an installer for a solution I'm developping, I'm using visual studio installer and InstallShield(for adding custom actions) for editing the msi. When I try to uninstall the product some of the exe files are not deleted however they have the same properties as the files that are deleted. By the way, Permanent option is set to false for all the coponents. Any help is appreciated

Here is a part of the log file

Answer 1

Log the uninstall and read through it. You may have reference counting and/or component rule violations that causes Windows Installer to leave the files out of an abundance of caution.
