[izpack-users] Detecting an upgrade

[Markus Schlegel]

1) Yes, look at the Registry Action in the documentation. Write your
ApplicationKey to the registry and read it to detect an old installation
before.

2) Yes, if you include the Registry Action like described in the
Documentation.

> well-known location). In this case I want the installer to behave
> differently. E.g. the installer should provide options to re-install the
> software or to uninstall it. Ideally it should also detect "upgrades",
> that is the case if the previously installed software has a lower version
> number than the one to be installed.

> 2) I see that IzPack optionally generates an uninstaller. On Windows, will
> those uninstallers automatically be registered in the Software registry?
