John, Just to elaborate, you cannot install a package where the product ID matches that of an already installed product. You should change either your product ID to * (which will create a new ID every time you build your MSI) or alternately, change it manually yourself.
I tend to do the latter and update it once per release version. If I try an install on my test system, and I have forgotten to regress back to a previous version or a completely clean machine, I get an error.
