Is the UpgradeCode the same in the old and new project?  If so you should get a clean upgrade as long as you are installing in the same context (all users or per user)

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


I have written a WiX installer for my application which was previously done by someone else using the Visual Studio Setup project. I am facing a major issue where the wix installer installs the application but does not overwrite the one installed using the setup installer. So there are two same applications installed in the end.

I need to fix this asap but I do not how how to go about this. Is there any way I can check if the application is installed, uninstall it and then install using the Wix installer. If not and in the worst case, I would be fine if I can at least display a message to manually uninstall the previous application before proceeding with the wix one.

Thanks a lot
