"Basic MSI" (I'm not sure why Flexera calls it that, but I assume to distinguish it from their "InstallScript MSI" projects) is just "MSI" as far as Microsoft is concerned. It is a bit different and you do not bother with the older InstallScript event handlers.
There is a couple of different sequences in MSI, UI and Execute, and you schedule the scripts/custom actions to run at the appropriate time in one or both sequences. Or you can have a script run during a dialog box action (DoAction)

It is a bit of a change of thought process, but anything is doable, especially when you consider you can call out to a C# DTF Custom Action as Christopher Painter describes here. In other words, from within an installer it should be possible to do anything that C# allows a person to do in code. Practically anything is possible.

The easiest way to get started with DTF custom actions is to install WiX on a system with Visual Studio installed. This gives a new project type under "Windows Installer XML" of "C# Custom Action Project". These DLLs can be called equally well from InstallShield as from WiX.
That's why Chris calls it "ISWiX" - it combines some of InstallShield abilities with some of WiX abilities.
Once you get a handle on that then it is easy to accomplish anything desired.
I hope that is helpful.
