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.

Do not worry. Windows Installer CleanUp Utility might be able to help. You can use the utility to remove installation information for programs that were installed by using Windows Installer. Be aware that Windows Installer CleanUp Utility 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.

Editor's note: The Windows Installer CleanUp Utility is provided "as is" to help resolve installation problems for programs that use Microsoft Windows Installer. If you use this utility, you may have to reinstall other programs. Caution is advised. We recommend that you do not use this utility with 2007 Office system products.
