.NET Framework Cleanup Tool is designed to automatically perform a set of steps to remove selected versions of the .NET Framework from a computer. It will remove files, directories, registry keys and values and Windows Installer product registration information for the .NET Framework. The tool is intended primarily to return your system to a known (relatively clean) state in case you are encountering .NET Framework installation, uninstallation, repair or patching errors so that you can try to install again.

Works very well and has fixed many issues I've had in the past.

BEWARE ! You may THINK this utility only removes OLDER versions of .NET framework, but it will remove all traces of ALL .NET framework installs on your computer !

shodan816, this is clearly explained on the main web page of this tool : This cleanup tool will delete shared files and registry keys used by other versions of the .NET Framework. If you run the cleanup tool, you will need to perform a repair/re-install for all other versions of the .NET Framework that are on your computer or they will not work correctly afterwards.
