It relies on Visual studio being present though, Nullsofts nSis (which I use) cares not for such restrictions. no it doesn't. It can be used with VS but you don't have to. When we started using WiX, I just used an XML editor create the files and then ran the WiX compilers and linkers from the command line. It's convenient to use it via Visual Studios, but by no means necessary.
