Hi Jacques, Yes, major upgrade removes previous version and if upgrade will be uninstalled, the whole product will be uninstalled. There is no support for going back to previous version. What you may or may not want in this case is uninstallable patch.

I install v1.0. Next, I install v2.0, replacing all the existing files and removing v1.0, assuming that I've used <RemoveExistingProducts After="InstallFinalize" /> in v2.0 My question is this. What happens when I uninstall v2.0? Everything I've read seems to indicate that the product will just be removed. Is it possible to have an uninstall of v2.0 rollback to v1.0? I've been searching for articles/blogposts regarding downgrades, but haven't been successful in finding any. Is the aforementioned scenario supported at all or will I need to manage this myself?
