[wix-users] WiX installer does not overwrite Visual Studio Setup application

[Suhaib Ahmad]

Thanks for your reply. I know now that at least I am going in the right
direction. My WiX installation is on a perMachine scope, whereas the Setup
project allows the user to choose between Only him (per user) or Everyone
(per machine). When I try running the old installer for all users, and then
install using the new WiX installer, there is only one application shortcut
in the Program Menu and Desktop, but there still are two entries in
the *Control
Panel > Programs and Features*.

Did not mention this earlier, but the WiX installer deployed is x86 and
defaults to *\Program Files (x86)\* but the VS setup installer is x64 and
defaults to \Program Files\

And yes I do have a MajorUpgrade element.
