MIDI Locator hasn't registered any components in the registry, so just delete the folder were you have copied the .zip content into.

The only thing which remains are the user entries in your registry for MIDI Locator. You could leave them there if you decide to reinstall MIDI Locator in the future, since they really don't need much space in your registry database.

But if you want your registry to be clean, delete the registry tree "HKEY_CURRENT_USER\Software\Rittberger Software". You don't need to do so, and you should not touch your registry, if you don't exactly know what you do, or you could damage your system!!!
