I have an existing product "A" completely unrelated to product "B". I need to uninstall "A" then install "B" all silently after the user invokes the install. Would you use the upgrade feature or something else? I have the MSI registry codes for both.
You didn't say what type of project you are using. This is easily done with Events in a Suite project. Use a Custom Action for Basic MSI or InstallScript MSI projects.

Hi
You can achieve it via custom action by
-mentioning uninstall command line of msi/exe you want to uninstall-https://stackoverflow.com/questions/36305662/how-to-uninstall-a-product-from-installshield -One more way via custom action-https://community.flexerasoftware.com/showthread.php?115449-Uninstall-Other-Installshield-MSI
If both installers are Basic MSI projects, just create a Major Upgrade item in the project for product "B" that specifies the UpgradeCode of product "A" with appropriate the product version.
