In my main package i install external msi using chain msi. During the build of the package the product code of the external msi is known and set in the dedicated combo box. When i remove the main package the uninstall process build a command line using the product code defined in the project and uninstall the external msi.

How it's possible to manage the new product code if the external msi has been updated through a hotfix or a patch ? Because if this external msi is updated, if i uninstall the main package, the external msi will not be uninstalled.
