While the Windows Installer Cleanup utility was found to be a very useful tool by many, as it resolved installation problems, it was also recently found 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 now no longer supports the use of this tool.
This utility has replaced Windows Installer Cleanup utility with Program Install and Uninstall Troubleshooter.
