If you're installing . Net before launching your msi you could also include an exe written in c# that detects your platform and then passes the answer back to your bootstrapper.
DotNetInstaller is probably what you need to use: you can create different "setup" configurations which will only be triggered if the right combination of OS, platform and language are met. You can also embed any MSIs, prerequisites etc. into the setup executable so users only have a single file to download/run.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
