Windows Installer Cleanup Utility

The Windows Installer Clean up Utility is planned to allow you to safely remove Windows Installer settings from your computer in the event of a problem. Windows Installer may turn into damaged if

Your computer's registry becomes corrupt. You or someone else unintentionally 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 broken up. There are multiple examples of Setup running simultaneously, or an instance of Setup is "blocked". The Windows Installer Cleanup Utility is designed to allow you to safely take out Windows Installer settings from your computer in the event of a difficulty. Although the Windows Installer is designed to be very robust, it is possible for Windows Installer to become damaged if:

1. Your computer's registry becomes corrupted.

2. You or someone else inadvertently changes a registry setting used by the

3. Windows Installer, resulting in a problem.

4. The installation of a program that uses Windows Installer (for example,

5. Microsoft Office 2000) is interrupted.

6. There are multiple instances of Setup running simultaneously, or an

7. Instance of Setup is "blocked."

           Windows Installer Cleanup Utility will eliminate all Windows Installer information associated with the selected programs; include 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 at present installed on your computer, the program will no longer be able to add or remove apparatus or to repair itself; to prevent problems; it is recommended that you reinstall your programs before you use them. The Windows Installer Cleanup utility (MSICUU2.exe) was a software utility for the Microsoft Windows operating system designed to resolve uninstallation problems of programs that use the Windows Installer technology. It looks up registry references and files related to Windows Installer that were installed by different programs, and forcibly wipes invalid entries out. It works in all 32-bit and 64-bit versions of Microsoft Windows.

        

  The utility was first released by Microsoft in 1999 to help Windows-based computers clean up installed programs that would either refuse or make up not to remove themselves from the add/remove programs feature in Microsoft Windows. The utility will just change registry values and files associated with the Windows Installer portion on the program. It will not remove many files from the computer and is only to be used as a last trough attempt when dealing with a buggy program. The utility can only be run by users who are logged in as system administrators. For developers who have problems with the Windows Installer automatically repairing their own installations on developer equipment (when the developer has manually updated some of the binaries), this utility is ideal to remove the Windows Installer information at the same time as leaving the actual installation intact.

      

  While the Windows Installer Cleanup utility was found to a be a very useful tool by many as it resolved installation problems, it was also recently established to damage some other components of the Windows operating system, installed on the  computer. Because of this reason, Microsoft has removed the Windows Installer Cleanup utility from its Download Center. Microsoft has created the Windows Installer Cleanup Utility which allows you to safely remove Windows Installer-related registry settings from your computer in the event of a problem. This utility from Microsoft allows you to clean out applications from the Microsoft Installer local file. If you ever get an app (that uses the MSI) that gets so screwed up you can't uninstall it, can't reinstall it, and you are preset, this application should allow you to tackle the problem. Once installed, you run the program "Windows Install Cleanup" from your Start menu. It will get a list of installed applications that use MSI. You can then eradicate any of them from the MSI database. The Windows NT description of the Windows Installer Cleanup Utility is Msicuu.exe, the Win9x and ME version is Msicu.exe.
