You could try WixCop. Exe to see if it'll translate to WiX v3: http://robmensching.com/blog/posts/2009/7/7/Tips-on-how-to-upgrade-from-WiX-v2-to-WiX-v3 .
Admittedly a guess but the best I can offer: Use the most recently available installer and deompile it with the current WiX toolset (your second option). Then modify as needed.
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.
