Hi all,
I have an InstallShield InstallScript MSI project.

I used the Major Upgrade option but with that approach what I see is that files of previous
version gets removed, registry entries get deleted, etc. However, the uninstallation logic that is in the
InstallScript (*.rul) files does not get executed and hence the uninstall of previous version is not complete.

Basically, it seems Major Upgrade does not execute InstallScript code? Please advise.
