Deinstallation of a product inside an installation

[Axel.Strasser]

Is there a possibility to define inside a msi the deinstallation of another
package (also msi based). In the "old" package there is no upgradecode
defined, therefore I can not use this. The custom action is not working
because I can not launch msiexec if there is already the msiexec running.
Any other ideas ?

msiexec should work in the UI sequence. But that won't help you if your
setup runs with Basic or no UI.
You could have a launcher exe uninstall the old version then start the new
setup.
