When you are working on your computer and installing a new program, the installation suddenly fails. Now you are left with a partly installed program.
You try to install the program again, but you are unsuccessful. Or, maybe you have problems trying to remove an old program because the installation files are corrupted.
This is where Windows Installer Cleanup Utility steps in. You can use the utility to remove installation information for programs that were installed by using Windows Installer. The program will not remove the actual program from your computer. However, it will remove the installation files so that you can start the installation, upgrade, or uninstall over.
