I've added a chained MSI package to an installshield project, but am finding that it is not getting installed during minor upgrades. I have added the following condition to the "Install condition" setting:
Not Installed OR REINSTALL><"FeatureName"
per the suggestion on this page: https://docs.revenera.com/installshield19helplib/helplibrary/ChainedMSIPackages.htm
The chained MSI package is successfully installed during a clean install, but not during upgrades.
Unfortunately Chained MSI's do not work with Minor Upgrades.
If you need to upgrade your software and also include chained MSI then you will need to create a Major Upgrade:
