We have a case where an older version of the product contained a component that is not shipped with the new version. The problem we are having is two-fold... first, the services are not being stopped, leading to forced reboots. Second, the files are not being removed.
Now, I am unsure if this is due to the authoring of the old installshield-built msi, or something I might not be doing properly in wix (using a custom bootstrapper around our msi). I can upgrade current version of the product without issue, so I'm suspecting the former.
What I would like to achieve, is a workaround (not against using a custom action) to handle the case of upgrades, where, if a pre-version 7.x product is found, then I fire a CA to stop those services and remove those files. How would I set out to achieve that?
