When you try to remove an assembly from the Global Assembly Cache (GAC) or C:\Windows\assembly, you get this error:

Unable to uninstall: assembly is required by one or more applications

You need to delete the registry entries first at:

\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Assemblies\Global
