Question : Visual Studio2008 integrated Windows Installer

I have a installer to package a .net app into an msi. I update the "Version" property every time i build a new .msi. Problem is when the msi is installed on another desktop that has the previous version, the exe file is not overwritten with the new one (user is forced to manually delete the exe and re-run the install). There are no install errors reported. Is there something I am missing ?
