Hi, when I rebuild my setup without any version change, then re-running the setup calls OnResumeUIBefore event. But i want to uninstalls the previously installed application. Please somebody help. It's urjent.
Please see the OnResumeUIBefore help topic for information about when that event is used. If you want to uninstall a previous build on a system when running a new version from InstallShield, there's a setting in Tools > Options for that; for a customer/target system, you'll need to change the version and define a major upgrade item.
