Run Windows Installer Cleanup Utility
Description of the Windows Installer CleanUp Utility
The Windows Installer Clean Up Utility is designed to allow you to safely remove Windows Installer settings from your computer in the event of a problem. Windows Installer may become damaged if:
* Your computer's registry becomes corrupt
* You or someone else inadvertently changes a registry setting used by the Windows Installer, resulting in a problem - The installation of a program that uses Windows Installer (for example, Microsoft Office 2000) is interrupted.
* There are multiple instances of Setup running simultaneously, or an instance of Setup is "blocked"
msi7.JPG (53915 bytes)Windows Installer Clean Up Utility will remove all Windows Installer information associated with the selected programs, including the entries for the programs in the Add/Remove Programs control panel. Note that the Installer information for that particular program is alone removed, not their files. If you remove the settings for a program that is currently installed on your computer, the program will no longer be able to add or remove components or to repair itself; to prevent problems, it is recommended that you reinstall your programs before you use them.
When you install the Windows Installer Cleanup Utility, three files are copied to the "C:\Program Files\Windows Installer Clean Up" folder, namely msicuu.exe, msizap.exe and readme.txt.
