Thanks for the heads up on the Clickteam installer software guys, great tool. I worked out how to install to any directory that the user chooses as well, works a treat. It seems that if you create a folder for your install files and compile it into a directory structure that mirrors the install path, it copies and overwrites each file to it's own given destination without a hitch. Because it overwrites files and not folders it is 100% safe to do it this way, unlike other installers i tried that refuse to cooperate. Each file has an install path that is copied from the directory structure you set up in the source folder, so obviously it's important to get that bit right.
