问题
I am working on a WPF desktop application and I am deploying through an install file generated by InstallShield Limited Edition. I would like the installer to prompt the user and remove any previous versions of the application before installing the new version. I suspect this is done via the Upgrade Paths option in InstallShield, but I can't get it figured out.
Answer goes to an explanation or a link to a decent how-to, tutorial or manual page that answers my question.
At the moment, when running the installer, I get: "Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel."
Thanks

Try this:
- in Solution Explorer go to "General Information" page
- increase the Product Version
- generate a new Product Code
- make sure that ALLUSERS property has the same value as in the old package
- go to "Upgrade Paths" page and add the old MSI
- build and install your new version
When running this new package it should automatically detect and remove older versions.
