The installer currently doesn't support that ... however ... there is no reason you can't move it manually after you install ...
I will add this to the list of things to do. An obvious suggestion, it is! I'm not an WiX installer expert ... otherwise I would just crack it out right now. :-)
I assume then that it's simply copying the files there and that there's no registry shenanigans going on then, correct?
Because it's not that big of a deal then!
