I have the following questions related to the installation on windows 1) Is it possible to define an installation as patch for the major release in a way that it will appear in the Control Panel under View Installed Updates 2) Is it possible to define an installation as “update/upgrade” that causes the previous version to be uninstalled and new version to be installed

The upgrade mode in InstallBuilder works differently - it updates the existing installation by adding the new and/or modified files to uninstaller information and updating version information in Add/Remove Programs.
As for uninstalling an application prior to installing it again, it is possible to check if uninstaller is present in specified location after
It can also be run in
It is also possible to read the location from registry and then run the uninstaller if appropriate registry key exists.
