In short, an MSI is a database with tables and logic that specifies where and how things should end up on the system. Custom Actions are the logic that performs custom operations within an MSI. This may not be rocket science, but I believe you need the right tools and a decent understanding of MSI to follow the flow. This was previously a gap in my ...
