Just did a complete reinstall of all my hosts and plugins, to go 64-bit only, and the Melda installers really stood out of the ones i installed. Everything is clear, the installation paths are being auto completed, and the installer works very quickly. May only be a small thing, but some installers can really be a pain the ***, for example on some, it's not clear whether the installer will create a folder like "Melda Productions" or not, which can easily mess up your folder hierarchy, if you are keen on having one. Also there's installers which add a "\Vstplugins" to the location you specified, and if you don't take care, you will end with a folder Vstplugins in your plugins folder, which obviously sucks. And sometimes it's not clear whether the installer adds an uninstaller to the system too, or simply creates the folders and files in the VST plugin folder... real nightmare if you have to install a lot of stuff, and you never know whether it is this or that way. But again, praise to the Melda installer, it's really great in these regards. 
Oh, and the updater is great too.
