I have developed installation of my application using InstallShield. When installation is built as a single self extracting executable, then everything works fine and splash screen is displayed while setup.exe is launched. However, when I changed the installation to be of type Downloader (which means two files setup.exe and setup.msi will be created separately) and I launch the MSI the splash screen is not displayed. How this can be implemented, Please suggest?
MSI doesn't have the ability to display a splash screen. As the file is getting processed by msiexec it will just show the default "Preparing to install..." message
If you want to display a splash screen it will need to be done by a separate bootstrapper.
