Windows Installer Logging

Windows Installer records errors and events in its own error log and in the Event log. The diagnostic information that the installer writes to these logs can help users and administrators understand the cause of a failed installation.

For more information about interpreting Windows Installer log files, see the white paper available on the TechNet site: Windows Installer: Benefits and Implementation for System Administrators.
