Drop the installer executable in the "Drop Installers Here" folder. Make sure there aren't any other .dll or .exe files in there.
Click "Install 1 File" from the setup menu.
The installation screens will come up. Follow the ptompts, making sure to install ONLY the VST (not the standalone app or any other plugin types). When the installer is done, use the Receptor's "Refresh Plugins" utility.
You can then load the plugin in demo mode, just to try it out. If it works for you, you can then register it pretty easily.
