Windows Installer Cleanup utility by Microsoft is a small tool that allows you to troubleshoot the problems with software installations that use MS installer. It is advised to use this package in the following cases:
- The computer's registry becomes corrupted.
- A registry setting that is used by the Windows Installer is
inadvertently changed, and this change results in a problem.
- The installation of a program that uses Windows Installer (for
example, Microsoft Office 2003) is interrupted.
- There are multiple instances of a setup program running at the same time, or
an instance of a setup program is "blocked."
This program is small and very simple in use. You have to:
- Download it from a link.
- Install it like any other program by running the setup file.
- Start it (Start->All Programs) and begin working.
Actual "fixing" consists of selecting the problem installation and clicking "remove", then installing the application again.
