Requiring source packages during installation, repairs, and even uninstall are common occurrences for some customers. The core issue is that Windows Installer needs the source location of the package and its files to install – and can’t find them automatically –
Slipstreaming Windows Installer patches is, technically, installing the MSP simultaneously with the MSI as a single transaction. This is, effectively:
msiexec /i D:\product.msi PATCH=D:\patch.msp
The applicable transforms (both the authoring changes and patch transforms) are applied to the MSI and the MSI is installed with those changes from the start.
