Windows Installer Cleaner

Installation and Patches produced by Windows Installer will keep a backup in %SystemRoot%Installer folder for the future operation such as configuration, uninstallation and so on. This is a very good thing, but if the installation is canceled or failed, Windows Installer will not delete the MSP or MSI file before it quit. When user run the installation again, a new MSP or MSI file will copy into the %SystemRoot%Installer folder with a new name and the previous MSP or MSI file will be useless. There are other solutions of Similar Algorithm on network. If you are using the 64-bit operating system, please be sure to confirm whether these solutions support 64-bit operating system.
