We had a requirement a few years that required us to detect the presence of D drive, and silently perform the installation in a folder structure. If the D drive was undetectable, it installed in the C drive. We were able to achieve this functionality by leveraging the InstallScript project.
Today, since this program has been redone from a VB6 program into a .NET 2.0, we are having difficulties achieving this because we are not exactly sure how to install the prerequisites (like .NET 2.0, MDAC, etc.) within this paradigm.
If we use the basic MSI project, we can put in the prerequisites, but do not know how exactly to detect if there is a D drive.
