Windows Installer Logging includes a verbose logging option that can be enabled on a user's computer. The information in a verbose log can helpful when trying to troubleshoot Windows Installer package deployment. You can enable verbose logging on the user's computer by using Command Line Options, the MsiLogging property, Logging policy, MsiEnableLog, and EnableLog method.
When the verbose logging switches 'x', 'v' and or '!' are enabled it can significantly impact Windows Installer performance compared to a machine without these switches set. The performance impact can vary between machines depending on hardware and configuration.
When the full verbose logging is turned on with the '!' switch it flushes every line to the verbose log during the install. If the Extra Debugging switch 'x' is set it has the potential to gather additional debug information depending on what custom actions are in the package. and can also cause a performance hit to the installation.
Full verbose logging with the '!' and 'x' are recommended for troubleshooting purposes. Turn off these switches if installation or uninstallation performance issues are a concern.
