Hi,

I've just started to learn how to use wise installer. I've been requested to write an installation for a new software package we designed. One of the specifications for the installation is that if there are future upgrades, the "old" version has to be uninstalled before the "new" version is installed.

Is there any way to force the software to uninstall before starting to install the new package?
