msizap.exe

The msizap.exe utility is part of the Windows Installer CleanUp Utility, a tool designed to help remove stubborn programs that cannot be uninstalled through normal Windows methods. In Windows 7, users may need to set msizap.exe to run with Vista compatibility and as administrator for it to function correctly. This utility is typically used alongside msicuu.exe, which provides the graphical interface for selecting and removing problematic installations. The tag covers troubleshooting scenarios where standard uninstallation fails, particularly with Windows Installer-based programs.
