Hi All,


we have setup created with Install Shield 6.x and is deployed at various client locations.

now we moved to Install Shield 2014. we created new InstallScript MSI project and recreated installer.


but when new installer is executed it doesn't detect & upgrade old installation.

in Upgrade table, we can't mention any upgrade code since IS6.x do not have upgrade code.


is there any way to upgrade or silent uninstall of old installation?


can anyone shad some light on how to upgrade previous installation created with IS6.x

You will have to run the uninstall command of the old setup (you could find it in registry).
