Msicuu.exe: Windows Installer Cleanup Utility
This GUI tool, the Windows Installer Cleanup Utility named Msicuu, safely removes Windows Installer-related registry settings from computers in the event of a problem. This tool allows you to select one or more Windows Installer programs from a dialog box and remove registry items that are related to the Windows Installer for the program or programs selected. The tool does not remove the Windows Installer; nor does it remove files of any Windows Installer programs such as Office 2000.
If you use this tool to remove the Windows Installer-related registry settings for a program and you plan to reinstall the program, you must install the program in the same folder to which you originally installed it. This prevents duplication of files on your hard disk.
This tool was designed to help resolve installation problems for programs that use the Windows Installer. Use of this tool may make it necessary to reinstall other programs. Caution is advised.
You can use Msicuu to correct the following installation failures:
A Windows Installer installation, uninstallation, or rollback is interrupted or fails unpredictably. Because the installation did not complete successfully, Windows Installer will not uninstall or reinstall the program, or install any another programs.
Registry entries for a product have been deleted or changed, damaging the operation of the products and preventing you from uninstalling or reinstalling the product.
Multiple instances of a setup program are running simultaneously, or an instance of a setup program cannot run.
Msicuu provides its own user interface.
Windows Installer manages the installation and removal of applications on Windows 2000, Windows XP Professional, and Windows Server 2003 operating systems. Typically, these installations conclude successfully, or are successfully reversed ("rolled back") or repaired. However, in rare situations, an installation, a rollback, or an uninstallation fails, leaving registry entries that would otherwise be removed. As long as these entries remain on the system, Windows Installer considers the installation to be active and incomplete.
Because Windows Installer conducts only one installation at a time, it will not start an installation until all indicators of the active installation are removed. You can use Msicuu to delete the registry entries remaining from a failed installation, thus allowing you to reinstall the product.
Windows 2000, Windows XP Professional, or Windows Server 2003
The user must be a member of the Administrators group on the computer.
Msicuu affects only the local computer. You cannot use it to manage a remote computer.
