This looks like such a promising work around for memory leaks but I'm falling at the first hurdle unfortunately; I've downloaded and installed a copy of Unity 4.6.4 but in the "Editor/Data/PlaybackEngines" folder I only have a folder called "WebPlayer". Have I missed a trick somewhere that means that Unity isn't creating the "windowsstandalonesupport" folder and the files that I need?
EDIT: Nevermind. I was looking in "Program Files/Unity" instead of "Program Files(x86)"
