We are upgrading our WIX msi installer (not a bundle) with manual pre-requisites to a Managed custom Bootstrapped application Bundle. The boot strapped custom installer bundle exe works fine for fresh installs. But if we want to upgrade our older product which is just an msi, we are in trouble. This is what I am trying to do
- Detect RelatedMsiFeatureHandler detects there is an older msi package installed.
- I am handling the Plan events for individual packages and setting the states as desired. For ex: state = Present for install
- I cannot to Apply(UpdateReplace) because I do not have an older Bundle,
The million dollar question is how do I upgrade this msi package? Any help is appreciated.
Thanks
